The key is to get dejagnu to identify the correct target for the tests.
Look for the most appropriate "*-sim.exp" in $srcdir/dejagnu/baseboards,
then run tests thusly:

	cd $build/gdb
	make check RUNTESTFLAGS="--target_board=foo-sim"

Separately installed tools are probably fine.  In a standard Cygnus toolchain
build tree, all the various programs (gcc, binutils, etc.) are built together
as siblings.  Perhaps such a combined source tree will exist in the public
GNU repositories too before long.
