[PATCH 0/2] MR6495: tools: Improve get_bindir on Windows targets.

[Jacek Caban (＠jacek)]

Currently, mingw-w64 has its own implementation of relocable widl support. With new Wine helpers, it may use Wine support instead and reduce the diff. This MR brings `get_bindir` in pair with mingw-w64's counterpart.
