Title: Fix config paths

This patchset should improve the handling of the paths for libgdiplus (by making it more consistent with that of other external libraries, yet preserving the possibility of building & testing Mono with a sibling non-installed libgdiplus) and for libMonoPosixHelper (in particular, fixing https://bugzilla.xamarin.com/show_bug.cgi?id=18555 )
