add bits/hwcap.h and include it in sys/auxv.h
aarch64, arm, mips, mips64, mipsn32, powerpc, powerpc64 and sh have cpu feature bits defined in linux for AT_HWCAP auxv entry, so expose those in sys/auxv.h it seems the mips hwcaps were never exposed to userspace neither by linux nor by glibc, but that's most likely an oversight.
