Either is fine. If you want 2 builds at the same time (release and 
debug) then you'll need to build outside the source tree. If you build 
in the tree, you have to clean out the build before you do another one.

At a guess... you could try CONFIG-=release and CONFIG-=debug_and_release.

If something is being modified late (like say, default_post.prf) then 
-after won't be enough and you'll need a hack like this.

cat >force_flags.prf <<END
CONFIG-=release
CONFIG-=debug_and_release
CONFIG+=debug
END
QMAKEFEATURES=$PWD qmake -r CONFIG+=force_flags
