Define _SYS_AUXV_H to 1 not empty in sysdeps/powerpc/sysdep.h


This is the last of the straightforward fixes for warnings I see
building for powerpc32 (hard-float, it's possible I might see more on
going back to soft-float testing having cleaned up the hard-float
noise).  sysdep.h defines _SYS_AUXV_H before including <bits/hwcap.h>
(this is a kludge to avoid errors from the test that <bits/hwcap.h>
isn't included directly by a user), but defines it to empty, when the
real <sys/auxv.h> defines it to 1, so resulting in warnings about
macro redefinitions when both headers get included in the same file.
Fixed by defining it to 1 in sysdep.h.

I don't plan to do anything about the warnings from sotruss-lib.c
about lack of powerpc support there, but hope the powerpc maintainers
(and, likewise, the sh and s390 maintainers) will deal with those.
