Revision 371610

- Fix stage-qa error where STAGEDIR was being referenced by the binary
  by setting up MAKE_ENV instead of passing STAGEDIR through PREFIX
- Respect CC, CFLAGS, LDFLAGS, and MAKE_JOBS
- Strip binaries
- Convert USE_BZIP2 to USES
- Use options helpers (this also fixes a problem where LIB_DEPENDS was
  being over-ridden in the PDF option, effectively cancelling out the
  LIB_DEPENDS for the PS option)
  Note: Did not use <OPT>_CONFIGURE_ENABLE because the configure script
  only understands --disable-<feature>
- Bump PORTREVISION
