 You mean this:

+  POWERPC_E200_MASK = MASK_VLE | MASK_ISEL | MASK_MULTIPLE

?  Well, this just marks that the e200 processor supports ISEL regardless 
of the mode selected (standard vs VLE).  Then with -mvle ISEL is supposed 
to be enabled regardless of the processor setting in effect (ISEL is a 
part of the base VLE instruction set, while it is optional in the standard 
mode).
