Sync top level files with versions from gcc.

top	* Makefile.def (target_modules): Add libphobos.
	(flags_to_pass): Add GDC, GDCFLAGS, GDC_FOR_TARGET and
	GDCFLAGS_FOR_TARGET.
	(dependencies): Make libphobos depend on libatomic, libbacktrace
	configure, and zlib configure.
	(language): Add language d.
	* Makefile.in: Rebuild.
	* Makefile.tpl (BUILD_EXPORTS): Add GDC and GDCFLAGS.
	(HOST_EXPORTS): Add GDC.
	(POSTSTAGE1_HOST_EXPORTS): Add GDC and GDC_FOR_BUILD.
	(BASE_TARGET_EXPORTS): Add GDC.
	(GDC_FOR_BUILD, GDC, GDCFLAGS): New variables.
	(GDC_FOR_TARGET, GDC_FLAGS_FOR_TARGET): New variables.
	(EXTRA_HOST_FLAGS): Add GDC.
	(STAGE1_FLAGS_TO_PASS): Add GDC.
	(EXTRA_TARGET_FLAGS): Add GDC and GDCFLAGS.
	* config-ml.in: Treat GDC and GDCFLAGS like other compiler/flag
	environment variables.
	* configure: Rebuild.
	* configure.ac: Add target-libphobos to target_libraries.  Set and
	substitute GDC_FOR_BUILD and GDC_FOR_TARGET.
