Log Message:
Fix broken amd64 build:
   - use -fPIC in all the needed places.
   - add USE_TOOLS+=gmake; this requires gmake to build properly.
   - add missing dir to PLIST.
Also fix some LP64 issues that warned but didn't break the build.

Note however that the SSL code will not work in an LP64 environment;
it relies heavily on being able to cast pointers to int without losing
information. The ssl option should probably be blacklisted on LP64
platforms.
