* Makefile.am(stmp-targ-include): Copy newlib.h to targ-include.
(install-data-local): Install newlib.h.
* Makefile.in: Regenerated.
* aclocal.m4: Ditto.
* configure: Ditto.
* configure.in: Add AM_CONFIG_HEADER to generate newlib.h based on
newlib.hin. Add AC_DEFINE_UNQUOTED entries for _ELIX_LEVEL
and _NEWLIB_VERSION to fill in newlib.h header file entries.
In AC_OUTPUT statement, unset ac_file so multilib support does
not use last ac_file temporary used in newlib.h configuration.

* newlib.hin: New template file for newlib.h.
* stamp-h.in: New file.
