Support LD_UNDER_TEST environment variable to test a different linker.
Issue an error if LD_UNDER_TEST isn't an absolute full path.
* testsuite/config/default.exp: If LD_UNDER_TEST environment
variable exists, set ld and LD to it and set up tmpdir/ld/ld.
Issue an error if LD_UNDER_TEST isn't an absolute full path.
