Jean-Marc Lasgouttes 3ef4db2ce4 Continue pre-spring cleaning of configure script
* build-type=profiling implies -fno-omit-frame-pointer in gcc. This allows sysprof to yield proper call trees
 * remove --enable-grpof option (the build type is enough)
 * remove --with-frontend option since we have only one frontend. Move stuff around and generally simplify the Qt detection code
 * do not check for bc anymore.
 * Update README.
