Actually, we support external toolchains older than gcc 4.9. So no, it
is not good to use gcc-ar unconditionally.
So, it's like I replied on the LTO-enabling patch for systemd, we need
a global Config.in option that tells us if the toolchain supports LTO
or not, and another if the user wants to use LTO.
Best regards,
Thomas
