With this patch, gdb still passes a -E big to sim_open in the erc32
simulator code and there is nothing to parse it at that level.

AFAIK the erc32 simulator is big endian only and should just eat
the option for at least endian == big.  My patch just ate the option
if it was either big or little and gave an error on any other value.
