Sorry for the delay. Indeed, the test at that line only accepts .c, .S,
and .asm files, where the latter should probably be removed now that
we've standardized on .S.

Of course, the change is bogus. I can only (half) explain this by the
change from LIB2FUNCS_STATIC_EXTRA to LIB2ADD_ST extra.
The trivial patch allowed a x86_64-unknown-linux-gnu x spu-elf cross to
finish the libgcc build, and at least the set of objects built before my
patch series is identical to the set built now.
Ok for mainline?
