abuild 3.6.x does this for us, so this will lead to build failures. Also
rebuild since we moved things to the wrong places (e.g. /usr/lib instead
of /usr/lib/glade) in most APKBUILDs
As of now we're using the buildttype 'release', which produces optimized builds
but without any usable debugging info, which makes debugging crashes impossible,
even if a -dbg subpackage exists. As such we should build in the buildmode
'debugoptimized' to offer proper debug symbols.
