Yeah, we pick up target-cc rather than target-gcc when running
"make check" from the top level dir because CC_FOR_TARGET is
passed down as CC (rather than GCC_FOR_TARGET).  Curiously, you
get target-gcc if you run "make check" from the ld dir.

Agreed.  I've applied the following, which also fixes another minor
bug with the test.  Since we are running $CXX we ought to check its
version rather than $CC, in case they happen to be different.

	* ld-selective/selective.exp: Remove check that $CC contains the
	string "gcc".  Do -dumpversion for $CXX.
