libc: drop NO_FP_LIBC support

NO_FP_LIBC was added in 2004 to save space by disabling FP support in
*printf()/*scanf(). The size benefit is negligible on modern systems
and conflicts with assumptions made by current base utilities.

Remove the option and always build libc with floating-point support.

General further adoption of SPDX licensing ID tags.

Mainly focus on files that use BSD 3-Clause license.

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.

Special thanks to Wind River for providing access to "The Duke of
Highlander" tool: an older (2014) run over FreeBSD tree was useful as a
starting point.
