/* Glibc's headers don't define PTRACE_GETVRREGS so we cannot use a
configure time check. Some older glibc's (for instance 2.2.1)
don't have a specific powerpc version of ptrace.h, and fall back on
a generic one. In such cases, sys/ptrace.h defines
PTRACE_GETFPXREGS and PTRACE_SETFPXREGS to the same numbers that
ppc kernel's asm/ptrace.h defines PTRACE_GETVRREGS and
PTRACE_SETVRREGS to be. This also makes a configury check pretty
much useless. */
