[PATCH] flex: license update

Nikolay Papenkov


LICENSE set in flex recipe looks as not correct. It is set as "BSD-2-Clause" since:

however per reviewing the sources - correct LICENSE-s for flex packages should be:

LICENSE = "BSD-3-Clause & LGPL-2.0+"
LICENSE_${PN}-libfl = "BSD-3-Clause"

"BSD-3-Clause" is explained by top-level COPYING file in flex source-tree (https://github.com/westes/flex/blob/v2.6.4/COPYING#L27).
* text does actually include third obligation (without the actual "3" numbering)
"LGPL-2.0+" is explained by src/gettext.h (https://github.com/westes/flex/blob/v2.6.4/src/gettext.h#L4)
* relevant for flex but not flex-libfl package (that is not utilizing gettext)

Can this be approved and if yes - can we expect this update to be upstreamed (including dunfell branch) ?
