generator programs don't need bitmap.c

- Subject: generator programs don't need bitmap.c
I happened to notice this while looking into something else. The only
reason bitmap.o is linked into the generator programs is, print-rtl.c
will print out bitmaps embedded in RTL. But that never happens for
the RTL used by the generators (or there would be other references to
bitmap_* functions in gen*.c), and print-rtl.c is already #ifdefed up
to avoid having to drag other things into the generators, so we can
add one more #ifdef and not link bitmap.o in.
Bootstrapped i686-linux (C only).
zw
* print-rtl.c (print_rtx <case 'b'>): Don't attempt to print
bitmap contents if GENERATOR_FILE is defined.
* Makefile.in (BUILD_RTL): Remove $(BUILD_PREFIX)bitmap.o.
($(BUILD_PREFIX_1)bitmap.o): Delete rule.
