elf/tst-auxv.c includes misc/sys/auxv.h, which ends up not actually being included due to the guard overlap, and getauxval becomes an implicit declaration and implicit pointer conversion which means, at best, the test isn't actually testing what it thinks it is and, at worst, it'll crash and burn on platforms where implict pointer conversion is a Very Bad Thing. * sysdeps/powerpc/bits/hwcap.h: Allow _SYSDEPS_SYSDEP_H guard as a synonym for _SYS_AUXV_H to allow direct inclusion. * sysdeps/sparc/bits/hwcap.h: Likewise. * sysdeps/powerpc/sysdep.h: Define _SYSDEPS_SYSDEP_H instead of _SYS_AUXV_H so we can include sysdep.h and sys/auxv.h together. * sysdeps/sparc/sysdep.h: Likewise.
