Well, the problem with musl is that now all glibc-based libraries (libc, 
libm, pthread, etc) have to become a BUILDRUN-DEPENDS for most ports. 
Right now ravenports provides everything except libc, libm, libpthread, 
libutil, and a couple of others.  If I went the musl route, these would 
both have to be provided and conditionally added as deps for linux.

pros: even more compatible across linux systems, dropping even glibc ABI 
cons: a lot of extra work, might need extra patches for pkg(8)

so using glibc covers many/most major systems.  supporting musl-based 
systems might be contract work, or at least something maybe somebody 
else would have to champion, at least for now.

for example, I'd rather spend the time bootstrapping solaris.  I'd get 
more bang for the effort IMO.

Anyway, ftigeot gave me the idea about musl and I looked into it, but 
with the extra cost and the fact some ports aren't buildable yet with 
musl and that glibc is already pretty compatible with systems, I didn't 
look into it further.
