[2/2] winegcc: Find winebuild.exe instead of winebuild on windows.

[Dylan Smith]

When the winebuild directory is specified using the -B option, (stored in
opts->prefix) the winebuild executable is searched for using the path(s)
provided using this option.  Previously a file named exactly "winebuild"
was searched for in all cases, but building on windows would require that
"winebuild.exe" be searched for in the build directory.  This check is done
in the spawn function used to invoke winebuild from winegcc.
