Yes, it's possible, but it's tough to get right.  Your best bet is
probably to install it in a different prefix, say `make install
prefix=/tmp/install-tree' and see whether it works.

If you really want to run it in the build tree, look at the definition
of CXX_FOR_TARGET in the top-level Makefile, and use that.
