Subject: Fix: Fix pkgconfig detection, and multiple subsequent build for
 Android (#833)

* Fixing lib detection based on build host for Android builds

* Fixing workaround according to jandegr's proposal

* Fixing subsequent Android builds (where rename fails because of pre-existing renamed files)
