ppc64le test build failure on glibc 2.23.

[Carlos O'Donell]

Carlos, Tulio,

I see the following when trying to make check for ppc64le:

../sysdeps/powerpc/test-get_hwcap.c:26:22: fatal error: sys/auxv.h: No such file or directory
 #include <sys/auxv.h>
                      ^
compilation terminated.

A test can't include "<sys/auxv.h>" because we don't have
a redirecting header in include/sys/ for auxv.h.

You either have to include "<misx/sys/auxv.h>" or add a
redirecting header.

How did you guys get this to compile? :-)

Cheers,
Carlos.
