[PATCH] Add ldconfig cache tag handling for AArch64
Hi folks,
Initial core code for AArch64 - allocate a tag number
FLAG_AARCH64_LIB64 and add code to handle it in ldconfig. Code to
follow on libc-ports to handle parsing ELF flags and using the new
tag. Follows on from the previous armhf patch in the same area.
=====================================================================
Add ldconfig cache tag handling for AArch64
* sysdeps/generic/ldconfig.h (FLAG_AARCH64_LIB64): New macro.
* elf/cache.c (print_entry): Print appropriate message for cache
entries tagged with FLAG_AARCH64_LIB64.
