RISC-V: Extend syntax for the multilib-generator
- Support expansion operator (*) in the multilib config string.
- Motivation of this patch is reduce the complexity when we deal multilib with
sub-extension, expand the combinations by hand would be very painful and
error prone, no one deserve to experience this[1] again!
