[PATCH] winegcc: Allow specifying 32-bit libdir via configure script.

[Jacek Caban]

64-bit Wine build has no informations about 32-bit configuration. We
have some heuristics in winegcc to find 32-bit libraries, but it may not
be enough. 32-bit libraries can be in an arbitrary place in 32-bit build
if it's using --libdir.

This patch makes it possible to instruct 64-bit build where to find
32-bit libraries, so that winegcc -m32 can work correctly in such config.
