hal_mk_defs is somewhat special. Look at the CDL in hal/arm/arch/...

    make -priority 1 {
        arm.inc : <PACKAGE>/src/hal_mk_defs.c
        $(CC) $(ACTUAL_CFLAGS) $(INCLUDE_PATH) -Wp,-MD,arm.tmp -o hal_mk_defs.tmp -S $<
        fgrep .equ hal_mk_defs.tmp | sed s/#// > $@
        @echo $@ ": \\" > $(notdir $@).deps
        @tail -n +2 arm.tmp >> $(notdir $@).deps
        @echo >> $(notdir $@).deps
        @rm arm.tmp hal_mk_defs.tmp
    }

It is probably worth figuring out what is actually going wrong. No
error message from gcc might mean gcc is actually working O.K. and you
have a silly problem with fgrep, sed, tail, etc...
