sync config/ between GCC and src

I've applied the following patches to the GCC and the src CVS tree in
order to get the config/ directory in sync again. The change to GCC is
merely a ChangeLog fixup.
Of the diffs added to src, I have checked that none of the changes
impact generated files in the rest of the src tree:
- src does not use the GCC_CHECK_UNWIND_GETIPINFO nor the
GCC_CHECK_EMUTLS macro anywhere,
- the other changes were either in comments only (license updates),
or not in files that serve as inputs to generated files.
I've also rebuilt the src tree with these changes on i686-pc-linux-gnu,
but that is pretty pointless in hashing out any potential issues, as the
latter set of changes are confined to ppc-aix, cygwin.
Cheers,
Ralf
