[PATCH] ld: work around pr17618 testcase failure

[Jan Beulich]

Some change from 2.26.1 to 2.27 causes the ld-x86-64/pr17618 test to
exhaust memory on a 32-bit host. Generally converting memory exhaustion
to "unsupported" may not be the best solution, but I couldn't think of
reasonable alternatives.

	* ld/testsuite/lib/ld-lib.exp (run_dump_test): Treat memory
	exhaustion caused by a test as unsupported.
