- fix broken behaviour if CONFIG_PF_* is set (result depends on
order of the various platform elifs!); change it to always use
platform detection by looking at preprocessor symbols, and
then (if CONFIG_PF_STRING *and* CONFIG_PF_* are set) check
that CONFIG and detection match;
- write design notes about interaction of CONFIG_PF_* and
platform detection.
w3i3m[v9].nmk: define both CONFIG_PF_STRING and CONFIG_PF_*.
