ppc64: ELFv2: Load TOC value in system call stub

This fixes a segmentation fault in the system call's error handling path with
dynamically-linked binaries on PowerPC64 little endian.  The system call stub
wasn't loading up r2 with the appropriate TOC value in its global entry point.

The r2 setup code comes from the FUNC_START macro in gcc [1] and an equivalent
one can also be found in the LOCALENTRY macro in glibc [2].

On the ELFv2 ABI (see [1]):
 - The global entry point is expected to load up r2 with the appropriate TOC
   value for this function.
 - The local entry point expects r2 to be set up to the current TOC.

The problem happened with dynamically-linked binaries because:
 - the system call is an indirect call (via global entry point) from the binary
   to the shared library, landing in the syscall stub  (which didn't load up r2
   with the TOC of the shared library)
 - its branch to __syscall_error is a direct call (via local entry point) within
   the shared library, landing in the function (which expects r2 to be set up to
   that TOC)
 - when the function attempts to store errno (in an address relative to the TOC),
   that address incorrectly pointed to a read-only segment -- segmentation fault.

The problem didn't happen with statically-linked binaries because the TOC value
wasn't different on that case.

Thanks and credits to Alan Modra and Ulrich Weigand, for helping with this and
pointing out the solution.
