I'd definitely suggest leaving out the --with-system-tzdata option
altogether if you're not certain it works.

This is a different problem; the --with-system-tzdata option wouldn't
affect that.

I think what may be happening here is that a postgres executable expects
to find itself in a full installation tree, ie if it's in /someplace/bin
then the timezone files are in /someplace/share, etc.  Did you do a full
"make install" after building, or did you just copy the postgres
executable?
