[bug#64345] [PATCH] gnu: Add reduce-csl.

[Nigko Yerden]

* gnu/packages/maths.scm (reduce-csl): New variable.
---
The package is built successfully on x86_64_linux (natively),
armhf-linux and aarch64-linux (via 'guix build --system=...' command)
architectures.

There is no reproducibility due to datestamp (printed each time the
program starts), rundom-number generator initialization in CSL 
(see csl/cslbase/csl.cpp), and maybe some other stuff.

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.")
