fix toplevel configure script to work in a release system

[Bart Veer <bartv at ecoscentric dot com>]

Bug 86597. This change to the toplevel configure script makes it look
for host-side support in all versions of a package, not just in
version "current". It also copes with the host-side sources being
relocated to tools/src - although that is probably something we want
to change for 2.1.

	* 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".
