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. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>
