bug#47428: Problems building the up-to-date "devel" manual for the website

[Mathieu Othacehe <othacehe@gnu.org>]

Hello Leo,

This variable is provided by guile-lib@0.2.7 while this derivation uses
guile-lib@0.2.6.1 from guix-1.2.0-17.ec7fb66.

I have restarted mcron which now uses guix-1.2.0-18.6e7ba45 and
guile-lib@0.2.7.

However, guile-lib@0.2.7 fails to build:

  MAKEINFO guile-library.info
/tmp/guix-build-guile-lib-0.2.7.drv-0/guile-lib-0.2.7/build-aux/missing: line 81: makeinfo: command not found
WARNING: 'makeinfo' is missing on your system.
         You should only need it if you modified a '.texi' file, or
         any other file indirectly affecting the aspect of the manual.
         You might want to install the Texinfo package:
         <https://www.gnu.org/software/texinfo/>
         The spurious makeinfo call might also be the consequence of
         using a buggy 'make' (AIX, DU, IRIX), in which case you might
         want to install GNU make:
         <https://www.gnu.org/software/make/>
