Subject: Patch: [PR 50562]: configure: add target-libgloss to skipdirs when
 using --without-newlib
From: "Jeremy Stenglein \(jstengle\)" <jstengle@cisco.com>

As per PR 50562, when --without-newlib is passed to configure,
target-newlib is added to skipdirs.  
But target-newlib is not added to noconfigdirs, so this check:
 
# If we aren't building newlib, then don't build libgloss, since
libgloss
# depends upon some newlib header files.
case "${noconfigdirs}" in
  *target-libgloss*) ;;
  *target-newlib*) noconfigdirs="$noconfigdirs target-libgloss" ;;
 esac

Does not disable libgloss like it should when 
--without-newlib is passed.  So the following 
patch adds target-libgloss to skipdirs when --without-newlib
is passed.

Testing: Bootstrapped/tested on x86_64-linux and sparc-sun-solaris2.10 
with a gcc+newlib+libgloss combined tree.

       * configure.ac: --without-newlib should add libgloss to skipdirs
       * configure: Regenerate.


Ok for trunk?

Thanks,
Jeremy
