[APPROVE] fix toplevel configure script as per 86597

[Bart Veer]

I believe this patch will fix the problems reported in 86597, and have
committed the changes to the trunk. It is probably a good idea for the
release branch as well, but somebody else should probably test it
first in their world.

	* configure.in, configure:
	Look for the host-side sources in tools/src as well as in host, as
	per the 2.0 release tree.
	Look for per-package host-side software in any/all versions of a
	package, not just "current".
