freebsd.h (LIB_SPEC): Key the exact setting to configure-time options and target version of FreeBSD.

	* 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.
	(CPP_PREDEFINES): Likewise.
	(PREFERRED_DEBUGGING_TYPE): Change to DWARF2_DEBUG.

	* config/alpha/freebsd.h (CPP_PREDEFINES): Moved to common freebsd.h.
	* config/i386/freebsd.h (CPP_PREDEFINES): Likewise.

/* Provide a LIB_SPEC appropriate for FreeBSD as configured and as
required by the user-land thread model. Before __FreeBSD_version
500016, select the appropriate libc, depending on whether we're
doing profiling or need threads support. At __FreeBSD_version
500016 and later, when threads support is requested include both
-lc and -lc_r instead of only -lc_r. To make matters interesting,
we can't actually use __FreeBSD_version provided by <osreldate.h>
directly since it breaks cross-compiling. As a final twist, make
it a hard error if -pthread is provided on the command line and gcc
was configured with --disable-threads (this will help avoid bug
reports from users complaining about threading when they
misconfigured the gcc bootstrap but are later consulting FreeBSD
manual pages that refer to the mythical -pthread option). */
