Thiago Macieira 1bd27f24fb Add link-time optimization support for Clang, GCC and ICC ... GCC currently requires fat object files for static libraries, since the linker would otherwise not load the .o file from the archive at all and the linking would fail with a lot of undefined references. Clang on Linux also needs this, but it has no equivalent flag, so enabling LTCG for Clang on static libraries will result in linker error. This commit does not add support for enabling it in configure. It can be enabled on a per-project basis by doing CONFIG += ltcg or by passing -config ltcg to qmake's command-line.
