That particular warning comes from cpplib, which is not currently
aware of __extension__ since it treats each token in isolation.

insn-*.c are compiled by the bootstrap compiler (in stage 1); do we
know that this compiler will, in truth, always accept the LL suffix?
If so, another possible change is to make -Wno-long-long override
-Wtraditional for this warning; that would be much easier to
implement.
