The static Qt modules in the base repository are already packaged as a
separate package (mingw-w64-qt5-base-static). This change applies the same
separation to Qt modules found in further repositories. That means it is no
longer required to build a static version of Qt if only shared libraries
are required.
Note that there's no static variant for mingw-w64-qt5-activeqt because this
module ends up being built as a static library anyways. There is also no
static version of mingw-w64-qt5-translations because it does not contain
any libraries.
It doesn't work because the otherwise the beginning of the path ends up in
the previous capture. This means the build must still be contained within
the top-level directory /build.
* Only packages for additional modules are covered so far
* Only packages for mingw-w64 target are covered so far
* This leads to small adjustments/unifications within the
PKGBUILDs; not tested yet
