This would allow us to keep the current naming as is, while still= supporting the the emul as supported by clang. This would be similar to the already existing targ_alias which is used to a= lias the target triples.=20 I believe (from a quick look) that this should all be do-able by modifying = configure.ac in a similar way as targ_extra_emuls currently does.
