[RFA]: Top-level configure patch to build Cygwin native newlib

[Corinna Vinschen <vinschen@redhat.com>]

Hi,

perhaps I could just apply the patch but I would like to ask people first
if there something is in the way of applying the below patch.

The idea is the following:  If you have a source tree containing the newlib
subdir but the source tree does not contain the winsup subdir, then it's
impossible to build a native Cygwin newlib.  The reason is, that building a
Cygwin native newlib requires a bunch of header files from the winsup/cygwin
directory.  If the winsup directory is missing, the build will break when
trying to build newlib.

For that reason, the below patch to configure.in checks if the winsup
directory is available and removes newlib from the target_configdirs
if winsup is missing.

Is that ok to apply?

	* configure.in: Don't build Cygwin native newlib if winsup
	directory is missing.
	* configure: Regenerate.
