windres currently looks for gcc in this order:

* target-prefixed gcc in same directory as windres
* gcc in same directory as windres
* gcc in PATH

In case of cross compiling the unprefixed gcc is a native compiler
and probably the wrong choice.

This adds another option to look for a target-prefixed gcc in PATH
in case binutils and gcc are installed in different prefixes.
