Hey Ludo,

The CI reports that core-updates evaluation is broken. That's because
"search-input-file" expects a relative FILE whereas some calls, such as
the one in the glib package provide an absolute one:

--8<---------------cut here---------------start------------->8---
(search-input-file (or native-inputs inputs)
                   (string-append
                    "/bin/python"
                    ,(version-major+minor
                      (package-version python))))))))
--8<---------------cut here---------------end--------------->8---

We could edit all those calls to use relative FILE arguments. Another
solution would be to make sure that search-input-file treats
"/bin/python" and "bin/python" the same way as proposed in the attached
patch.

That would be consistent with search-input-directory that already
accepts both "/include/xxx" and "include/xxx".

WDYT?

Thanks,

Mathieu
