[Win] configureapp produces invalid QT_CL*_VERSION in qconfig.pri with non-English MSVC output

The newly introduced compiler version pattern matching regular expression produces invalid output for the QT_CL_*_VERSION variables when using an MSVC installation that produces non-English output (as many seem to do by default these days).

In my case, it matched almost the whole line and a new line that then corrupted the qconfig.pri so much that the build failed with a rather unrelated error message (z_compress2 and z_uncompress not resolved) due to the configuration containing garbage.
