Okay, I was able to build this on x86_64 and cross-build to i686. Would
anyone like the test the build on armhf or mips64el?

I was able to run a "Hello world" program [0]:

---
$ ./pre-inst-env guix environment --pure --ad-hoc erlang -- erl -noshell -eval 
'io:fwrite("Hello, world!\n"), init:stop().'
Hello, world!
---

The configure script was not finding OpenSSL, so I've modified the
package locally to provide the path.

I did something similar for `rm`. Also, I had to provide the path to
`sed` in 'erl/bin', which is just a small shell script.

I've attached my changes. What do you think?

The Nix package [1] might show the way for future improvements to this
package.

For example, the documentation (man pages) is distributed separately, so
I've attached a patch that adds them in their own package. But, they are
only 6 megabytes (erlang itself is 100 megabytes), so they should
probably be folded into the the erlang package.
