Patch to update libtool in GCC and Src trees

[Charles Wilson]

This is a copy of a message sent privately to Steve, only this version 
does not include the following attachments:
    gcc-toplevel-changelog-fragment
    src-toplevel-changelog-fragment
    newlib-libtool-update.changelog.bz2
    add-to-toplevel.tar.gz
    newlib-libtool-update.patch.bz2
Mainly because newlib-libtool-update.patch.bz2, even compressed, is 
360k.  Hopefully Steve will be able to integrate these with his changes 
and post the whole thing.

I think you should post the entire combined patch.  My piece is 
attached, but there are a few things you need to do, in additional to 
your changes, and in addition to incorporating the patch:

in the gcc tree
(1) add 'compile' from automake-1.9 to toplevel (I've put a copy in the 
attached 'add-to-toplevel.tar.gz' file)

in the src tree
(1) add 'compile' from automake-1.9 to toplevel
(2) remove newlib/libtool.m4
(3) apply the attached patch at the newlib/ level.

And, of course, revise and extend your ChangeLog entries for 
gcc-toplevel, src-toplevel, and src-newlib.  (See attached)

With the addition of a patch to fix a separate, recently-introduced 
problem: http://www.cygwin.com/ml/newlib/2007/msg00558.html , I obtained 
the following results:

On cygwin-native, I successfully built a new cygwin kernel with its 
internal newlib. The build process did NOT create any libtool scripts, 
nor did configure run any of the libtool-related tests (except for the 
SED one).

On linux-native, I successfully built a shared newlib library, and the 
build process did create and use several libtool scripts.
