Hi,
shouldn't this also be added for MIPS? This commit added a file called
hwcap.h:
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=e14f1db7a61f016d74393ca9e8fc49a91d27f603

that commit seems to failed to add it to Kbuild
so it is never installed (i checked installed
uapi headers only because looking at the kernel
source tricked me previously)
but i guess the intention is clear in this case
so we can add it..

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.
