[CRIS] Don't internal error if forced big endian
This fixes:
$ ./gdb -q -ex "set endian big" -ex "set architecture cris"
The target is assumed to be big endian
.../src/gdb/cris-tdep.c:4051: internal-error: cris_gdbarch_init: big endian byte order in info
A problem internal to GDB has been detected,
further debugging may prove unreliable.
Quit this debugging session? (y or n)
The "set cris-version" command can likewise cause internal errors.
The gdbarch init routine should be returning 0 to reject the
architecture instead of internal erroring on user input.
gdb/ChangeLog:
2016-03-09 Pedro Alves <palves@redhat.com>
* cris-tdep.c (cris_gdbarch_init): Return 0 if the info's byte
order is BFD_ENDIAN_BIG or if the cris version is unsupported.
