[PATCH] Add ldconfig cache tag handling for ARM hard-float ABI


Hi folks,

Initial core code for armhf ABI - allocate a tag number
FLAG_ARM_HFABI and add code to handle it in ldconfig. Code to follow
on libc-ports to handle parsing ELF flags and using the new tag.

=====================================================================

Add ldconfig cache tag handling for ARM hard-float ABI

	* sysdeps/generic/ldconfig.h (FLAG_ARM_HFABI): New macro.
	* elf/cache.c (print_entry): Print appropriate message for cache
	entries tagged with FLAG_ARM_HFABI.
