IANAL...

Indeed it's not.

According to the SPDX FAQ [0]:

  * How does one handle [...] licenses not found in the SPDX License
    List?

    [...] one can add the license text to the SPDX file and define a new
    license label. That license identifier is defined only for that
    specific SPDX document. This is explained in Section 6 of the SPDX
    Specification or see [1].

However, we do not have our own SPDX document in Buildroot, so section 6
does not apply.

However, we already have similar situations, where we simply state
something like:

    FOO_LICENSE = Foo license

So, I would state something similar here:

    PERL_TERMREADKEY_LICENSE = Term::ReadKey license or Artistic-1.0-Perl

Please double-check which versiopn of the Artistic license this is
refering to (i.e. the docs says "see the full text of the license in the
file "Artistic" that should have been provided with the version of perl
you are using.", so I just used Artistic-1.0-Perl but I'm not sure...)

Regards,
Yann E. MORIN.
