— Rename ofzip to ofarc
It supports more than just ZIP now, so the name was no longer
appropriate. (user: js, size: 45919) [annotate] [blame] [check-ins using]

— configure: Prefix Clang-only flags with -Xclang
This is required for systems for which Clang does not know how to call
the linker, as Clang then just calls GCC for linking, passing all flags.
However, GCC does not know the Clang-only flags and fails to link. (user: js, size: 46038) [annotate] [blame] [check-ins using]
