Builds of go-ipfs for musl libc about distributions

[Kubuxu]

We might get away with linking all binaries always completly statically with musl. What do you think about that?

Here is a post about something like this: http://dominik.honnef.co/posts/2015/06/statically_compiled_go_programs__always__even_with_cgo__using_musl/

But I am not sure about it.

Or we can just do a docker build and grab the binary from the image

<@lgierth> whyrusleeping: do you mind if i patch a linux-musl-amd64 tarball of fs-repo-migrations into dist.ipfs.io for now? i'll see to getting musl into dist proper
<@lgierth> uggh and the auto-migrations code in go-ipfs needs to figure out that it's musl
<@lgierth> aha ok, ldd which ipfs | grep libc | grep musl

I've patched a musl build into fs-repo-migrations: https://ipfs.io/ipns/dist.ipfs.io/fs-repo-migrations/v1.1.0/fs-repo-migrations_v1.1.0_linux-musl-amd64.tar.gz

It has been built with the go-ipfs docker image, by running go get -u github.com/ipfs/fs-repo-migrations and then grabbing /go/bin/fs-repo-migrations from within the container.
