Another option would be to build the files in question with -ffreestanding
(and to make sure the optimization is disabled if -ffreestanding is used --
if it is not, that is a bug).  That makes sense to me: those files are
part of the implementation of the C library, so GCC can't assume that
there is a C library already when compiling those files.
