Instead of an aarch64-w64-mingw32-pkg-config, you can configure with 
--pkg-config=pkg-config, and set PKG_CONFIG_LIBDIR=<your/lib/pkgconfig>.

That said, this patch seems like a consistent followup to 
e5163b1d34381a3319214a902ef1df923dd2eeba - so either we apply this, or 
decide to scrap the non-pkgconfig fallback for this library. (Applying 
this patch in the meantime probably doesn't hurt, while deciding on 
whether pkg-config can be required here.)
