libc: further adoption of SPDX licensing ID tags. 2017-11-25T17:12:48+00:00 Pedro F.

The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts.
