Commit "45aabcddc5 utils/get-developers: really make it callable from
elsewhere than the toplevel directory" had a unforeseen side-effect:
the fact that check-developers with no arguments used to validate the
syntax of the DEVELOPERS no longer works. Indeed, the
parse_developers() call was moved *after* the check that verifies if
at least one action is passed. Due to this, the check-DEVELOPERS
verification in Gitlab CI, which invokes get-developers without
argument to validate the DEVELOPERS file... no longer does anything
useful.
In order to fix this, we introduce an explicit action in
get-developers to request the validation of the DEVELOPERS file. The
implementation is trivial, as the validation is already done by
calling parse_developers(), but at least now we have an action that
does "nothing", except execute until the validation is done.
This is also much more explicit than "invoke get-developers without
arguments to just do validation".
The initial investigation of the issue was done by Ricardo Martincoski
<ricardo.martincoski@gmail.com> and reported at
https://patchwork.ozlabs.org/project/buildroot/patch/20220528014832.289907-1-ricardo.martincoski@gmail.com/,
but we have chosen to introduce a separate -v option rather than
making the validation part of the existing -c action, which serves a
different purpose.
