Re: ECL and musl

Hey,

I'll update bundled GC before next release. One of the valid scenarios 
where bundling GC with ECL makes sense is static linking (and ECL 
supports that – when GC is bundled it is statically linked and none of 
its symbols are exported). I've also found it handy, when I was buidling 
ECL on NetBSD, which shipped only non-threaded build of bdwgc.

Note, that ECL first looks for system GC and if it can be used – it is.

Regards,

Daniel
