Such objects may have been generated in a transitional period when
ABI tags were not added to all objects.

	* sysdeps/unix/sysv/linux/arm/dl-cache.h
	[__ARM_PCS_VFP] (_dl_cache_check_flags): Allow plain FLAG_ELF_LIBC6.
	[!__ARM_PCS_VFP] (_dl_cache_check_flags): Likewise.
	* sysdeps/unix/sysv/linux/arm/readelflib.c (process_elf_file):
	Set FLAG_ARM_LIBSF for soft-float ABI otherwise just FLAG_ELF_LIBC6.
