Its not a bad idea but the xcrypt dependencies would get ugly as it
would have to depend on glibc without using the default deps as you
say.

I think we're close to making it work with the virtual/crypt, at least
for nativesdk and since this matches what we'll likely ultimately have
to do, I'm tempted to go that route.

Current patchset is missing a musl PROVIDES but that is easily fixed
for the next test.
