Thanks, I committed it on HEAD as follows (AC_ARG_VAR implies AC_SUBST).

        * m4/as.m4 (AM_PROG_AS): Let CCAS and CCASFLAGS default to the actual
        values of $CC and $CFLAGS (as opposed to $(CC) and $(CFLAGS)), so
        configure tests can use them.  Use AC_ARG_VAR instead of AC_SUBST.
