# Using CFLAGS here may be confusing if the user has given a special
# CFLAGS intended for use on the host, since we are passing it to the
# cross-compiler; I'm not sure what to do about this.  INCLUDES is
# from the top level Makefile.
# FIXME: But isn't CFLAGS what is used to pass multilib options when
# building the library?
