Title: Use `override` with `-fPIC` option so it is ALWAYS included

I'm a little dissatisfied with the `CFLAGS_add` solutions in `Make.inc`. `make` gives us two behaviors for assigning variables: those that the user can overturn easily (`=`, `+=`, `:=`) and those that they cannot (prefixed with `override`). By creating a nonstandard variable name, we create a second tier of overridable values in the Makefile.

I think it would be more straightforward for everyone involved if we just separate the Makefile into default `{C,F}FLAG` values, and those that cannot be overridden, added onto the `{C,F}FLAG` values via `override`.
