move it from a BUILD+RUN_DEPENDS to WANTLIB+LIB_DEPENDS so that the dependency
is tracked and opal gets updated if the FFmpeg API changes. Comment to explain
why check-lib-depends says it's extra. Pointed out by Brad, ajacoutot@ hates
it but is ok with it.
- add -fPIC unconditionally (requested by naddy@) by adding it to
unix.mak (in pwlib) which get sourced by the other ports
feedback from and ok naddy@, thanks!
OPAL is an open-source class library for the development of applications
