ltmain.in: Pass through -fdiagnostics-color, -frecord-gcc-switches

* -fdiagnostics-color: who doesn't like color? No reason to strip it. This
  makes the link phase stick out like a sore thumb if there's warnings emitted.

* -frecord-gcc-switches: we use it in Gentoo to check if a package respects
  *FLAGS. Note that we do not need to include -grecord-gcc-switches explicitly
  here as -g* is already whitelisted.

* build-aux/ltmain.in: Handle -fdiagnostics-color* & -frecord-gcc-switches.
