[PATCH] Powerpc: Add support for openat and fstatat syscalls

[Carl Love]

GDB maintainers:

The following patch adds the sycall support for the openat and fstatat
system calls.  The missing support results in gdb.reverse/fstatat-
reverse.exp reporting a failure.

The following patch adds the support.  The testcase runs without any
failures.  The patch was tested on a Power 9 system.

Please let me know if the patch is acceptable for mainline.  Thanks.

                        Carl
