Yes. So i decide to stick with Cyrille suggestion and use
CFLAGS:= ${CFLAGS:N-O*:N-pipe}
CXXFLAGS:= ${CXXFLAGS:N-O*:N-pipe}
to avoid just -O and -pipe while keeping other user defined flags untouched.

Yes, but i'm not sure that i skilled enough in things like that, i just
can say that it doesn't working with optimization flags, and working
without.
There is updated (and i believe finished) version of port:
