since commit 22edeb3f4 (private; anno 2002), the generator would extract -prebind and translate it into a PREBINDING property in the pbx file. the writeout to the pbx file got lost in the rewrite for Xcode 3.2 (commit 66f6e5b1; anno 2012). this isn't particularly bad, as prebinding is obsolete since OS X 10.3.4. we now go the last mile and remove the handling of the flag. that means that remaining projects which still use it (meaninglessly) will get a warning from Xcode, which is kinda what we want. QMAKE_LFLAGS should have never been part of the library iteration loop. it was added there in the prebind handling commit, so we can get rid of it again now.
