A working guix package

[drewc]

This works as described in the readme. Should add some toplevel install docs but for 0.18.1 it's fine as is.

LGTM.

However:

1. Is make core working for you? Somehow I had to make bootstrap && make from-scratch instead in Nixpkgs.
2. Shouldn't you be replacing the "gcc" by a hermetic link to a static gcc, as I do in Nixpkgs?
3. Shouldn't you use --enable-march= to avoid non-portable instructions on a public package?

1. Is make core working for you? Somehow I had to `make bootstrap && make from-scratch` instead in Nixpkgs.

Yes, it's now working fine. For 0.17 I had to build the bootstrap, package that, build gambit, package that, then build.sh gerbil with those deps.

Now it seems to work just by the three steps. However I have not tried to build on all my guix boxes from scratch so it may be working by fluke. I'll make sure.

2. Shouldn't you be replacing the `"gcc"` by a hermetic link to a static gcc, as I do in Nixpkgs?

I'm not sure that's needed.

3. Shouldn't you use `--enable-march=` to avoid non-portable instructions on a public package?

I thought that march-native was to enable mass gcc optimizations? The package is built with gcc on a GNU system. Where did I go wrong?

--enable-march=native will work better on the same (kind of) machine that compiles it, at the expense of not working on other machines. So if you have a fancy recent Intel64 CPU, the binary won't run on an old AMD64 CPU, and vice versa.
