Re: [build] Cleanup rs6000/t-ppccomm configurations (PR other/51022)

This does the trick.  You could also use
	case ${host}:${with_multisubdir} in
	    *:*32*)
		;;
	    powerpc64-*:* | *:*64*)
		tmake_file="$tmake_file rs6000/t-linux64"
		;;
	esac
in config.host, but that's unnecessarily complicated.  The t-linux64
bits can safely go in other config files.  Bootstrapped and regression
tested powerpc-linux and powerpc64-linux.

	* config/rs6000/t-linux64: Delete.  Move..
	* config/rs6000/t-ppc64-fp: .. softfp_wrap defines to here..
	* config/rs6000/t-linux: ..and libgcc flags to here.
