sim: accept -EB/-EL short options

Browse Source 
Many GNU tools accept -EB/-EL as short options for selecting big &
little endian modes.  While the sim has an -E option, it requires
spelling out "big" and "little".  Adding support for -EB & -EL is
thus quite trivial, so lets round it out to be less annoying.
