[PATCH 2/4] OpenMP 4.0 offloading to Intel MIC: liboffloadmic.

	* Makefile.def: Add liboffloadmic to target_modules.  Make
	liboffloadmic depend on libgomp's configure, libstdc++ and libgcc.
	* Makefile.in: Regenerate.
	* configure: Regenerate.
	* configure.ac: Add liboffloadmic to target binaries.
	Restrict liboffloadmic for POSIX and i*86, and x86_64 architectures.
	Add liboffloadmic to noconfig list when C++ is not supported.

config/
	* target-posix: New file.

libcilkrts/
	* configure.tgt: Use config/target-posix.
