[GOLD][PATCH] Avoid generating .ARM.attributes section in output if merging none from input.

Hi Ian,

    This patch fixes a problem during kernel build.  The kernel
building process uses ld -r multiple times and it sometimes produces
intermediate objects with no code and data.  Previously we emitted an
empty .ARM.attributes section with all default values and set the EABI
version to unknown.  That caused the objects to be considered not
empty and the EABI version info and attributes merged.  We should
ignore such objects like ld.

	* arm.cc (Target_arm::do_finalize_sections): Do not emit an
	.ARM.attributes section if we have not merged any input
	attributes sections.
