	FreeBSD system configuration merged from mainline.

	* config.gcc (the unlabeled system switch statement): Add
	generic configuration section to handle *-*-freebsd*.  Also,
	to match the system compiler, default to threading support (it
	may be disabled with the standard --disable-threads
	configuration-time switch).  Report bad configuration.

	* config/freebsd.h (LIB_SPEC): Key the exact setting to
	configure-time options and target version of FreeBSD.  Set-up
	to match architectural change in threading support.  Correctly
	report when -pthread option is not supported by configure-time
	options.
	(FBSD_CPP_PREDEFINES): Move from architecture-specific files
	and extend to encode target version number in run-time setting
	of __FreeBSD__ macro to match the system compiler.  Use #endif/#if pair
	instead of #elif (which is OK for this case but not in general).
	(CPP_PREDEFINES): Likewise.
	(PREFERRED_DEBUGGING_TYPE): Change to DWARF2_DEBUG.

	* config/alpha/freebsd.h (CPP_PREDEFINES): Moved to common freebsd.h.
