254 --with-tune is ignored if -mtune is specified; likewise --with-tune-32

256 --with-float is ignored if -mhard-float, -msoft-float, -mfpu, or -mno-fpu

259 here, otherwise say -mcpu=v7 would be passed even when -m64.
260 CC1_SPEC above takes care of this instead.
261
262 Note that the order of the cpu* and tune* options matters: the
263 config.gcc file always sets with_cpu to some value, even if the
264 user didn't use --with-cpu when invoking the configure script.
265 This value is based on the target name. Therefore we have to make
266 sure that --with-cpu-32 takes precedence to --with-cpu in < v9
267 systems, and that --with-cpu-64 takes precedence to --with-cpu in
268 >= v9 systems. As for the tune* options, in some platforms
269 config.gcc also sets a default value for it if the user didn't use
270 --with-tune when invoking the configure script. */
