[PATCH 2/3] ld: map option for run_dump_test requires no program.

[Andrew Burgess]

When using run_dump_test with the map option to compare the linker map
file produced, no additional dump program should be required.  A dump
program can still be given if needed, but leaving it off will no longer
produce an error.

ld/testsuite/ChangeLog:

	* ld/ld-lib.exp (run_dump_test): When using the map option, no
	program is required.
