Make the linker return an error status if it fails to merge ARM binaries with
different architecture tags. Add a test case to make sure that this works,
and update readelf so that it will not seg-fault when trying to display the
attributes of binaries with invalid architecture tags.
* elf32-arm.c (elf32_arm_merge_eabi_attributes): Return false if
failed to merge.
* ld-arm/attr-merge-arch-2.d: New test case.
* ld-arm/attr-merge-arch-2a.s: New test case source file.
* ld-arm/attr-merge-arch-2b.s: Likewise.
* ld-arm/arm-elf.exp: Run new test case.
* readelf.c (display_arm_attribute): Use unsigned int type for
tag, val and type variables.
