Final(?) patch to update libtool in GCC and src trees

[Paolo Bonzini]

> OK to checkin?

I checked in the patch to fix the as/ld/nm problem on cygwin, but there 
are still other issues to be solved.  However, I'm sure we can first of 
all limit your pain in maintaining the patch.  So, if you wish, you can 
checkin everything *but the new libtool* after testing on just one 
platform (combined tree, or separate gcc/src builds are both okay), with 
the changes I indicate below.

The patch is preapproved with those changes, but please post it again.

Obviously leave this out for now too, and keep config-ml.in in sync 
between gcc and src.

Here, please add -I .. to Makefile.am's ACLOCAL_AMFLAGS instead of 
modifying acinclude.m4.
