gas: rx: constify string to rx_error

[Mike Frysinger <vapier at gentoo dot org>]

building rx's gas code atm fails:

rx-parse.c: In function ârx_parseâ:
rx-parse.c:3774:9: error: passing argument 1 of ârx_errorâ discards âconstâ 
qualifier from pointer target type [-Werror]
../../../gas/config/rx-defs.h:40:12: note: expected âchar *â but argument is of 
type âconst char *â
cc1: all warnings being treated as errors

2011-10-19  Mike Frysinger  <vapier@gentoo.org>

	* config/rx-defs.h (rx_error): Add const to first arg.
	* config/rx-parse.y (rx_error): Likewise.
