We assume ELF everywhere now, so drop support for non-ELF.

The hard-float ABI will now use /lib/ld-linux-armhf.so.3.
We detect the use of the hard-float ABI and select the
appropriate dynamic linker name. You must have a new or
patched compiler which also uses the new dynamic loader
name when the hard-float ABI is selected.
This header uses __set_errno(), so make sure we include errno.h for it.
Otherwise, if INLINE_SYSCALL() is used and errno.h isn't included, we
hit warnings like so:
In file included from libc-start.c:36:0:
../sysdeps/unix/sysv/linux/dl-osinfo.h: In function '_dl_setup_stack_chk_guard':
../sysdeps/unix/sysv/linux/dl-osinfo.h:79:7: warning: implicit declaration of function '__set_errno'
Which culminate in errors like so:
libc-start.c:(.text+0x692): undefined reference to '__set_errno'
libc-start.c:(.text+0x752): undefined reference to '__set_errno'
collect2: ld returned 1 exit status

The ia64 math code has extra matherr functions (f and l variants),
so add them to the libm.so plt whitelist like the existing matherr
in the main code.
The check-localplt test now passes.

For the most part, these are adding symbols from newer glibc releases that
should have been added to ia64 in the first place, but no one noticed.
There were also adding symbols from older versions, but that appears to be
an oversight in the old abilist files where the ia64 tuple wasn't added to
the symbol block.
A few symbols did get deleted, but that looks normal as no other arch has
them, and comparing to an old glibc-2.7 build, things have been this way
for quite a while.
After this, `make check-abi` now passes for ia6.

These are the abilists as ia64 had them before being removed from the
main tree. Most libs pass, but a bunch need updating. That'll be done
in a follow up commit.

The main tree updated the dl-tls code to use a new GET_ADDR_PARAM macro.
We need to define that to fix a build error due to it missing.

Building a lot of glibc files trigger warnings like so:
.../ucontext.h:52:25: warning: variably modified '_pad' at file scope
The ia64 header protects the use of __builtin_offsetof by a C++
compiler, but this builtin works just fine with C compilers, so
allow it to be used there too.

This applies the same updates that already exist in the main tree for
making the pthread_attr_t union more standards compliant.

All other ports have __scalbn* aliases pointing back to scalbn*, but
the ia64 code had omitted them. This didn't really matter as none
of the common code called them, but after a recent update, that's no
longer true. Add the aliases needed by some common code to fix link
errors with libm due to them missing.

The main tree dropped support for !__STDC__ code, so drop it from the
few places in the ia64 code too.

The ia64 math code stubs out the existing [er]_rem_*.c files, but the
main tree has added a new one since its removal. Stub out that new
file too.

The main tree decided to drop support for pre-ISO C code, so we
can use "const" instead of "__const".

This was done mostly by looking at the processed crt{i,n}.S files in
glibc-2.15, and then added the required update for using in either
csu/ or nptl/.
Seems to work -- when an earlier version didn't call the initializers,
many tests (pthread related) failed.

Logic specific to ia64 used to live in the main tree in common files.
Now that we can't do that (with #ifdef and such), we need to add that
logic into dedicated overriding files.

We need to update the file paths after the ia64 code was moved from
the main tree to ports/. In the case of backtrace.c, the main tree
actually copied the ia64 version to the x86_64 code, so we can go
ahead and drop the ia64 version.
