aarch64: Add hwcap string routines
Add support for routines in dl-procinfo.h to show string versions of HWCAP entries when a program is invoked with the LD_SHOW_AUXV environment variable set and also to aid in path resolution for ldconfig. * sysdeps/unix/sysv/linux/aarch64/dl-procinfo.c (_dl_aarch64_cap_flags): New array. * sysdeps/unix/sysv/linux/aarch64/dl-procinfo.h (_dl_hwcap_string, _dl_string_hwcap, _dl_procinfo): Implement functions.
