elf: Remove LD_HWCAP_MASK / tunable glibc.cpu.hwcap_mask
Remove the environment variable LD_HWCAP_MASK and the tunable
glibc.cpu.hwcap_mask as those are not used anymore in common-code
after removal in elf/dl-cache.c:search_cache().
The only remaining user is sparc32 where it is used in
elf_machine_matches_host(). If sparc32 does not need it anymore,
we can get rid of it at all. Otherwise we could also move
LD_HWCAP_MASK / tunable glibc.cpu.hwcap_mask to be sparc32 specific.
