[bug#66606] [PATCH] gnu: Add reduce-csl.

[Nigko Yerden]

* gnu/packages/maths.scm (reduce-csl): New variable.
---
This patch introduces Reduce, a general purpose computer algebra
system similar to Maxima.

The package is built successfully on x86_64_linux (natively),
armhf-linux and aarch64-linux (via 'guix build --system=...' command)
architectures.

Reduce became build-reproducible since the upstream revision 6601, but
the current "stable" snapshot 6547 is not reproducible.

The source code contains bundled fox and editline libraries as well
as their adjustments, which are difficult to remove. Also it contains
libffi (can be replaced by libffi from guix repo), crlibm and
softfloat (currently are not present in guix repo) libraries.

+system for doing scalar, vector and matrix algebra by computer, which also
+supports arbitrary precision numerical approximation and interfaces to gnuplot
+to provide graphics.  It can be used interactively for simple calculations but
+also provides a full programming language, with a syntax similar to other
+modern programming languages.  REDUCE supports alternative user interfaces
+including Run-REDUCE, TeXmacs and GNU Emacs.  This package provides Codemist
+Standard Lisp (CSL) version of REDUCE.  It uses gnuplot program, if installed,
+to make figures.")
