avr: simplify some option parsing with strcasecmp ()

     Instead of canonicalizing the argument we can just use a case insensitive
     compare.

gas/ChangeLog:

2016-04-03  Trevor Saunders  <tbsaunde+binutils@tbsaunde.org>

	* config/tc-avr.c (md_parse_option): Use strcasecmp () to compare
	strings.
