GCC (I think since about 4.7) provides wrappers for ar, nm and ranlib
with a "gcc-" name prefix (e.g. gcc-ar-4.7).
I created a topic to pick these up for CMAKE_AR, CMAKE_RANLIB and
CMAKE_NM per default if used with GCC.
These wrappers pass the --plugin option to the actual tools which is
required for link time optimization (LTO).
I haven't merged it to "next" yet since I am not sure if this might
break anything in existing setups.
Does anyone else have any insight or suggestions?
