[bug#60372] [PATCH v2] gnu: lisp: Add lfe.

[jgart via Guix-patches via <guix-patches@gnu.org>]

* gnu/packages/lisp.scm (lfe): New variable.

Here's a v2 but this a WIP as the tests are disabled. Unless we can
merge this and enable the tests later after we figure out whether we
want to do that with rebar-build-system or via a custom phase?

I have an issue open here asking about running the tests:

https://github.com/lfe/lfe/issues/450

I tried running the tests by manually calling rebar but I get a homeless-shelter write error.

For test commands that I tried see the following section in the lfe project's CI:

https://github.com/lfe/lfe/blob/develop/.github/workflows/cicd.yml#L36

If anyone would like to collaborate on this patch feel free to make
changes and just list me as co-author with you.

all best,

jgart
