- Try to fix parallel builds: setting ALL_TARGET to "depend all" would not

work in -jX case due to races; thus, move depend generation to pre-build
- While here, convert USE_GMAKE and fix badly indented line by one tabstop
- As advised by the Porter's Handbook, terminate URL with a slash (in port
  description text)
