	* config/arm/arm.opt (mcpu, march, mtune): Make case-insensitive.

Don't forget the leading tab; and since someone else will have to commit
the patch for you, you should also include the date/author part as well.
 Generally

<date>  Alan Lawrence  <Alan.Lawrence@arm.com>

would be acceptable, since the commit date may not be the same as the
posting date.

Otherwise, this is OK.
