[PowerPC] [PowerPCSPE] Fix multiple issues in fpsetmask().

Building R on powerpc64 exposed a problem in fpsetmask() whereby we
were not properly clamping the provided mask to the valid range.

This same issue affects powerpc and powerpcspe.

Properly limit the range of bits that can be set via fpsetmask().

While here, use the correct fp_except_t type instead of fp_rnd_t.

libc: further adoption of SPDX licensing ID tags.

Mainly focus on files that use BSD 2-Clause license, however the tool I
was using mis-identified many licenses so this was mostly a manual - error
prone - task.

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.
