Authentication-results: sourceware.org; auth=none

The option -m[no-]apcs-float was never implemented in GCC.  Since it
referred specifically to the FPA floating point co-processor which is
no-longer supported in GCC the option is now irrelevant.  This patch
cleans up the hunks that were left behind.

        * arm.opt (mapcs-float): Delete option
        * arm.c (arm_option_override): Remove hunk relating to
	TARGET_APCS_FLOAT.
        * doc/invoke.texi (arm options): Remove documentation for
	-mapcs-float.

Applied to trunk.

R.
