The only way to override LD, AR, OBJCOPY, and GPROF is through
--with-binutils (setting the environments variables on configure is
overridden by LIBC_PROG_BINUTILS).
The build-many-glibcs.py (bmg) glibcs option generates a working config,
but not fully concise (some tools will be set from environment variable,
while other will be set from $CC --print-prog-name). So remove the
environment variable set to always use the "$CC --print-prog-name".

The assembler is not issued directly, but rather always through CC
wrapper. The binutils version check if done with LD instead.

Commit 87d583c6e8 replaces the sed script
with an "objdump -f" invocation to determine the 'OUTPUT_FORMAT' bit of
the libc.so linker script.
However, when cross-compiling, for example from x86_64-linux-gnu to
aarch64-linux-gnu, "objdump -f" would report the wrong
format ("elf64-little"). Conversely, "aarch64-linux-gnu-objdump -f"
reports "elf64-littleaarch64" as expected.
This patch changes 'configure.ac' to use AC_CHECK_TOOL rather than
'$CC -print-prog-name=objdump' to determine the value of the OBJDUMP
variable. That way, OBJDUMP is set to TRIPLET-objdump when
cross-compiling for TRIPLET.

GCC does not print the correct linker when -fuse-ld=lld is used with
the -print-prog-name=ld:
$ gcc -v 2>&1 | tail -n 1
gcc version 11.2.0 (Ubuntu 11.2.0-7ubuntu2)
$ gcc
ld
This is different than for gold:
$ gcc -fuse-ld=gold -print-prog-name=ld
ld.gold
Using ld.lld as the static linker name prints the expected result.
This is only required when -fuse-ld=lld is used, if lld is used as
the 'ld' programs (through a symlink) LIBC_PROG_BINUTILS works
as expected.
Checked on x86_64-linux-gnu.

When LIBC_LINKER_FEATURE is used to check a linker option with the equal
sign, it will likely fail because the LD -v --help output may look like
`-z lam-report=[none|warning|error]` while the needle is something like
`-z lam-report=warning`.
The LD -v --help filter doesn't save much time, so just remove it.

The arguments of the LIBC_SLIBDIR_RTLDDIR macro are used both in unquoted
and single quoted context, so that neither shell nor makefile variable
references work. Consistently put them in single quotes so that they can
refer to makefile variables.
With all the machinery we just added, we can easily arrange to work even
when the compiler passes in -fstack-protector automatically: all the
necessary bits of glibc are always compiled with -fno-stack-protector
now.
So tear out the check in configure, and add appropriate calls to
-fno-stack-protector in tests that need them (largely those that use
-nostdlib), since we don't yet have a __stack_chk_fail that those
tests can rely upon. (GCC often provides one, but we cannot rely on
this, especially not when bootstrapping.)
When stack protection is disabled, explicitly pass -fno-stack-protector
to everything, to stop a compiler hacked to enable it from inserting
calls to __stack_chk_fail via the PLT in every object file.
In preparation to fix the --localedir configure argument we must
move the existing conflicting definition of localedir to a more
appropriate name. Given that all current internal uses of localedir
relate to the compiled locales we rename to complocaledir.
This patch continues removing architecture-specific cases from
non-architecture-specific files by moving the logic to use directories
such as /lib64 out of sysdeps/gnu/configure.ac.
A new macro LIBC_SLIBDIR_RTLDDIR is created that sysdeps configure
scripts can use to declare the library directories to be used; the
logic was previously duplicated in configure fragments for aarch64,
mips and x32 as well as in sysdeps/gnu/configure.ac. This macro is
used directly in sysdeps/gnu/configure.ac only to provide the /lib
default (the logic saying that with --prefix=/usr shared libraries go
in /lib not /usr/lib); the architecture cases formerly there are moved
into various new or existing configure.ac files. The new macro is
also used in the various architecture fragments that already had such
logic. In the x32 there was previously a configure fragment, but it
was a directly written one without a .ac file; now a .ac file is used
there instead to generate configure.
Tested x86_64 that the installed shared libraries, and the directory
structure of the installation, are unchanged by this patch.
There is an old bug report - bug 6441 - about library directories
changing after reconfiguring. If this is still applicable - and I
haven't attempted to confirm it or review the old patch pointed to in
that bug - then this patch should reduce the number of places needing
changing in any fix.

This change does two things:
* Treats a target i386-* as if it were i686.
* Fails configure if the user is generating code
for i386.
We no longer support i386 code-generation because the i386
lacks the atomic operations we need in glibc.
You can still configure for i386-*, but you get i686 code.
You can't build with --march=i386, --mtune=i386 or a compiler
that defaults to i386 code-generation.
I've added two i386 entries in the master todo list to discuss
merging and renaming:
http://sourceware.org/glibc/wiki/Development_Todo/Master#i386
The failure modes are fail-safe here. You compile for i386,
get i686, and try to run on i386 and it fails. The configure
log has a warning saying we elided to i686. There is no situation
that I can see where we run into any serious problems.
The patch makes the current state better in that we get less
confused users and we build successfully in more default
configurations.
The next enhancement would be to add --march=i?86
as suggested in #c20 of BZ#10062 for any i?86-* builds, which
would solve the problem of a 32-bit compiler that defaults to
i386 code-gen and glibc configured for i686-* target. Which
previously failed at build time, and now will fail at configure
time (requires adding --march=i686).
Updated NEWS with BZ #10060 and #10062.
No regressions.
