[OE-core] Architectures with underscores in their names, how to handle that?

[Koen Kooi]

Hi,

I'm working on adding support for big-endian armv8 and the toolchain people decided that it should be named 'aarch64_eb'. That currently works in OE because there isn't a 'eb' override yet, but there might be one in the future.

So my question is, how can I safely handle a name like this?

regards,

Koen
