ld/testsuite: Initialise a variable to prevent tcl errors

In some cases a variable could be left uninitialised and then an attempt
made to read this variable, resulting in a tcl error.  This commit
initialises the variable in all cases.

ld/ChangeLog:

	* testsuite/lib/ld-lib.exp (run_dump_test): Initialise
	check_ld(terminal).
