Ping^5/update: contribute Synopsys Designware ARC port (1/7): configuration


Since I posted the port the last time, there have been a number of changes
as well in GCC trunk as in the port, so a new patch set is required to
build the port in trunk.

Sanity-checked by bootstrapping i686-pc-linux-gnu.

OK to apply?
toplevel:

2013-02-25  Simon Cook  <simon.cook@embecosm.com>

	Changes to build configuration to allow big endian ARC ELF toolchain
	* configure.ac: Also add target-libgloss to noconfigdirs for arceb-*-*.
	* configure: Regenerate.

gcc:

2013-04-03  Joern Rennecke  <joern.rennecke@embecosm.com>
            Brendan Kehoe  <brendan@zen.org>
	    Simon Cook  <simon.cook@embecosm.com>

         * config.gcc (arc*-*-elf*, arc*-*-linux-uclibc*): New configurations.

libstdc++-v3:

2012-08-16  Joern Rennecke  <joern.rennecke@embecosm.com>

	* acinclude.m4 (GLIBCXX_ENABLE_SJLJ_EXCEPTIONS): Also check for
	_Unwind_SjLj_Register when deciding if to set enable_sjlj_exceptions.
	* configure: Regenerate.

contrib:

2013-09-05  Joern Rennecke  <joern.rennecke@embecosm.com>

	* config-list.mk: Add arc configurations.
