I had kept a full log of the build.

It looks as if libgcc/xfgnulib.pico is built twice, the first time by
the default rule, the second by the explicit ".c.o" one in
src/external/gpl3/gcc.old/lib/libgcc/libgcc/Makefile which doesn't pass
in CPPFLAGS.

I was using -j 8 to build this if it makes any difference.
