Subject: re PR driver/69805 (ICE in greater_than_spec_func, at gcc.c:9722)

	PR driver/69805
	* gcc.c (LINK_COMMAND_SPEC, GOMP_SELF_SPECS): Use
	:%* in %:gt() argument.
	(greater_than_spec_func): Adjust for expecting only numbers,
	if there are more than two numbers, compare the last two.

	* testsuite/libgomp.c/pr69805.c: New test.
