One of my recent patches broke the toplevel configury.  I moved a test
of $configdirs to a point before nonexistent directories have been
removed from configdirs.  The test was for whether gcc is being
configured.  The test is fine in the gcc repository, but not in the src
repository.

This patch fixes the problem.  If the gcc directory exists, we assume
that we are going to build it.  This only matters for setting the
default value for --enable-bootstrap.

Bootstrapped on x86_64-unknown-linux-gnu.  OK for mainline?

	* configure.ac: Set have_compiler based on whether gcc directory
	exists, rather than on whether gcc is in configdirs.
