Given that licenses such as "GPL-2.0+" are deprecated by SPDX, shouldn't we
instead introduce the canonical "GPL-2.0-only" and "GPL-2.0-or-later"?
And then add mappings for, e.g., "GPL-2.0" to "GPL-2.0-only" and "GPL-2.0+"
to "GPL-2.0-or-later".

Looking at https://spdx.org/licenses/exceptions-index.html, there is a long
list of predefined exceptions and "Linux-syscall-note" is just one of them.
We probably want a more generic solution for how to handle exceptions.
