Fabrice, All,

Thanks for looking into all those missing licensing terms. That's much
appreciated. :-)

You are referring to a license file in the rtai-lab/ sub-directory, but
we explicitly disable building of rtai-lab altogether with
--disable-rtailab:
    https://git.buildroot.org/buildroot/tree/package/rtai/rtai.mk#n27

And the GNUMakefile.am will not include the rtai-lab/ subdirectory
when --disable-rtailab is used:

    if CONFIG_RTAI_LAB
    OPTDIRS += rtai-lab
    endif

So this is probably not the correct license file we should be using.

The 'addons' subdir is conditional to CONFIG_RTAI_DRIVERS_SERIAL or
CONFIG_RTAI_DRIVERS_16550A or CONFIG_RTAI_CPLUSPLUS or
CONFIG_RTAI_COMEDI_LXRT or CONFIG_RTAI_RTDM, and they all default to
'no' if not explicitly enabled, and we do not explicitly enable any of
those.

So, it seems only the 'base' subdir is used. And in that subdir, we can
find a few files which bear a "GNU Lesser General Public License" notice
too.

So, the licensing terms are a bit more complicated than what this patch
suggestes.

Could you review this more in depth, and provide a commit log that
explains all the resultant licenses and license files, please?

Regards,
Yann E. MORIN.
