[PATCH] Print offending diff when check-abi fails

[Siddhesh Poyarekar <siddhesh at redhat dot com>]

The earlier version of check-abi would print a diff of the expected
ABI vs the built ABI when there was a difference.  Bring back this
behaviour.

	* Makerules (check-abi): Dump diff of symlist if the test
	fails.
