use CPPFLAGS at configure time

Yeah, it doesn't *have* to be used for .s files, but it's not like it
hurts either, especially at configure time.  Also, I find it much
nicer to be consistent and use the same flags wherever we run the
compiler.

Besides, I'm (ab)using CPPFLAGS in the mips64-linux configury to pass
-mabi= to the compiler, and this affects the code generated by the
assembler.  If this patch can't go in, I'll have to switch to CFLAGS,
duplicating autoconf's logic for a default CFLAGS, which I'd rather
not do.
