OK, yes, we should be using run_host_cmd everywhere we invoke a
compiler in the ld testsuite.  One reason being that run_host_cmd
properly inserts $gcc_B_opt in cases where a user wants to test
binutils with a newly built compiler, ie. when $CC specifies -B.

I'm going to apply this one too.

	* testsuite/ld-elf/no-section-header.exp (binutils_run_test):
	Use run_host_cmd to invoke $CC.
