a01f19c8fb i386: Fail at configure time for i386 builds. 
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.

d755bba40f Preserve errno across _PC_CHOWN_RESTRICTED call on XFS 
Fix BZ #15305.

On kernel versions earlier than 2.6.29, the Linux kernel exported a
sysctl called restrict_chown for xfs, which could be used to allow
chown to users other than the owner.  2.6.29 removed this support,
causing the open_not_cancel_2 to fail and thus modify errno.  The fix
is to save and restore errno so that the caller sees it as unmodified.

Additionally, since the code to check the sysctl is not useful on
newer kernels, we add an ifdef so that in future the code block gets
rmeoved completely.

7a86be6e5f Don't add input group during initgroups_dyn in hesiod 
Fixes BZ #15304.

The *initgroups_dyn functions are called with a group argument.  This
group gid is usually skipped while populating the grouplist since the
caller adds that group id in advance.

The hesiod initgroups_dyn implementation however adds the group gid to
the list if it does not already exist.  While it works fine for the
usual initgroups, it breaks nscd since it calls initgroups_dyn with -1
as the gid (to have all groups included).

6f2e90e78f Make mantissa type of mp_no configurable 
The mantissa of mp_no is intended to take only integral values.  This
is a relatively good choice for powerpc due to its 4 fpus, but not for
other architectures, which suffer due to this choice.  This change
makes the default mantissa a long integer and allows powerpc to
override it.  Additionally, some operations have been optimized for
integer manipulation, resulting in a significant improvement in
performance.

adbb8027be Remove PIPE_BUF Linux-specific code 
Fixes BZ #12723

The variable pipe buffer size does nothing to the value of PIPE_BUF,
since the number of bytes that are atomically written is still
PIPE_BUF on Linux.

ba384f6ed9 C++11 thread_local destructors support 
This feature is specifically for the C++ compiler to offload calling
thread_local object destructors on thread program exit, to glibc.
This is to overcome the possible complication of destructors of
thread_local objects getting called after the DSO in which they're
defined is unloaded by the dynamic linker.  The DSO is marked as
'unloadable' if it has a constructed thread_local object and marked as
'unloadable' again when all the constructed thread_local objects
defined in it are destroyed.
