Update rebuild rules in non-automake directories.

In <http://gcc.gnu.org/ml/gcc-patches/2009-06/msg02137.html>, I posted a
first set of changes against GCC trunk that update the rebuild rules for
files generated by the autotools. This patch was already approved, but
I wanted to defer its application until I had done the respective one
for src. Now's the time.
In the process, I found files I had omitted in that first patch. So
here is a second patch, against src (and overlapping with GCC), that I
am seeking approval for. I will then apply both combined, to both GCC
and src, where they apply. AFAICS they fix rules throughout the
binutils-gdb parts of src (i.e., what the git copy covers).
Notes:
- The intl and libdecnumber change is to please make implementations
where '#' comments does not extend across backslash-newline. It was
forgotten from the same (already posted) patch against GCC.
- The gdb change also fixes a bug with regeneration triggered by the
automake-generated makefile below the gnulib directory. This was
mentioned on this list a while ago, but I can't find a reference to it
now. Is there a PR attached to it that I should mention in the
ChangeLog?
There are changes unique to src (etc/) and to gdb in this patch, as well
as changes to files shared; a build system maintainer for GCC and src
should be able to approve this rather trivial patch, I hope.
Thanks,
Ralf
