f036d759ec gcc: Add 'mcf' thread model support from mcfgthread

	model

gcc/ChangeLog:
	* config/i386/mingw-mcfgthread.h: New file
	* config/i386/mingw32.h: Add builtin macro and default libraries
	for mcfgthread when thread model is `mcf`
	* config.gcc: Include 'i386/mingw-mcfgthread.h' when thread model
	is `mcf`
	* configure.ac: Recognize `mcf` as a valid thread model
	* config.in: Regenerate
	* configure: Regenerate

libatomic/ChangeLog:
