[bug#41013] [PATCH] Add gccmakedep util

[Jean-Baptiste Note]

Dear Guix maintainers,

I'm attempting to package x2go, and gccmakedep from the xorg utils is
required for the build.

This is therefore an attempt to package it -- so as to be able to use it
as native-input -- even though it is a deprecated tool.

There are two flavors of the patch:

- a -tar version which relies on a standard xorg mirror for download,
  and does not need the maintainer tools to build. Unfortunately guix
  lint reports a problem in that the tarball is not mirrored on software
  heritage.

- a -git version which is a bit more convoluted to build (requires
  maintainer tools as native-inputs: autoconf, automake, xorg macros),
  but with no failure in guix lint.

Please also note that /some/ elements from this xorg subdirectory are
prefixed with util- -- i've chosen not to include it here.

Please pick your choose, and let me know how to proceed!

Kind regards,
Jean-Baptiste
