cairo: Fix build with gcc 4.9
Fix upstream bug
https://bugs.freedesktop.org/show_bug.cgi?id=77060
gcc 4.9 now generates slim objects when LTO is used
These slim objects only contain intermediate language
representation for LTO. Use -ffat-lto-objects to create files which
contain additionally the object code. When linking some .so file, the option
'-flto' is missed, so the error happens.
We add '-ffat-lto-objects' flag to make gcc 4.9 behaves the same as gcc 4.8.
