[PATCH] RTEMS thread model configuration

The command line to build a GCC for RTEMS contained virtually always a
'--enable-threads'.  This patch helps to avoid this extra configuration
command line parameter and makes the GCC build a bit more user friendly
for RTEMS.

This patch should be applied to GCC 4.9 branch and master.

	* config.gcc (*-*-rtems*): Default to 'rtems' thread model.
	Enable selection of 'posix' or no thread model.
