We've got the same situation at work.  What I'm using right now to build
11-current _at_ r264151 is this:

	WITH_GCC=yes \
	WITH_GNUCXX=yes \
	WITHOUT_CLANG=yes \
	WITHOUT_CLANG_IS_CC=yes \

But that's now several weeks out of date, and there are two new knobs I
haven't investigated yet: WITH_CLANG_BOOTSTRAP and WITH_GCC_BOOTSTRAP.
