The linker must not throw away the lto.o file. We now instruct the linker to create a non-temporary lto.o, dependent on the target name. In order to do that we introduce a new mkspec variable QMAKE_LFLAGS_LTCG_SEPARATE_DEBUG_INFO. This variable can contain single-$ variable references that get evaluated when loading ltcg.prf.
