	* config.gcc: Remove all stanzas for previously obsoleted
	systems.  Where necessary, add explicit error stanzas to
	prevent removed systems from being misidentified as something
	else.  Begin a fresh obsoletions list, with the systems that
	were reprieved last round.
	* doc/install.texi: Remove all mention of dead targets.
	* fixinc/mkfixinc.sh: Likewise.

	* config/arm/arm.h: Bit 31 of target_flags is no longer
	reserved.
