Hi Renato,

This patch is really MIPS specific. But I think the problem is actually more general. Now, for example, we have three "environment" GNU, EABI, and Musl and "HF" ABI variants for each of this environment. If we support more C libraries, we will have to add new `Environment` items for each supported environment+ABI pair. Something like NewLib, NewLibHF etc. The idea of this patch is to separate notions of Environment and ABI and escape growing the `Environment` enumeration if we need to add new ABI for existing "environment".
