[Patch 6/6] ARM attributes: LD testsuite

[Andrew Stubbs <ams at codesourcery dot com>]

This patch adds some tests into the ld testsuite. They cover many of the
features of setting and merging attributes.

OK?

	ld/testsuite/
	* ld-arm/arm-elf.exp (armeabitests): Add EABI attribute merging 3,
	EABI attribute merging 4, and EABI attribute merging 5,
