b82ba2f011 MIPS: Respect the legacy syscall restart convention.
That convention requires the instruction immediately preceding SYSCALL
to initialize $v0 with the syscall number.  Then if a restart triggers,
$v0 will have been clobbered by the syscall interrupted, and needs to be
reinititalized.  The kernel will decrement the PC by 4 before switching
back to the user mode so that $v0 has been reloaded before SYSCALL is
executed again.  This implies the place $v0 is loaded from must be
preserved across a syscall, e.g. an immediate, static register, stack
slot, etc.

The restriction was lifted with Linux 2.6.36 kernel release and no
special requirements are placed around the SYSCALL instruction anymore,
however we still support older kernel binaries.

176f2fe0a1 tilegx: fix ldd to work with both tilegx64 and tilegx32
This uses the same ldd-rewrite.sed hook as other platforms, with
the minor tweak that tilegx uses /lib (64-bit) and /lib32 (32-bit).

2bc2d8e823 tile: fix DWARF bug in clone() for created thread
Previously, we would see a bad frame in the gdb backtrace output, e.g.:

  (gdb) bt
  #0  foo () at foo.c:5
  #1  0x000000aaaab68ee8 in start_thread () from /lib/libpthread.so.0
  #2  0x000000aaaad01c88 in clone () from /lib/libc.so.6
  #3  0x0000000000000000 in ?? ()

With this change the bogus frame #3 is gone and we have the
same output as x86 does for the same program.

7514f09e1e alpha: Fix redefinition of __isnanl macro warning
In bdd7898a58 we added self-definitions
of __isnan and friends in order to indicate specialized architecture
support, and avoid redefinitions within various generic math_private.h.

There is no generic math_private.h that concerns ldbl-128, and while
we provide __isnanl in the alpha math_private.h there's no need to
protect the function against redefinition.
