33# Some of these architectures are built in parallel (see i386_PARALLEL and
34# sparc_PARALLEL). This requires building some parts first before parallel build
35# can start. Platform make files know what should be built as a prerequisite for
36# the parallel build to work. The i386_PREREQ and sparc_PREREQ variables tell
37# which platform directory to enter to start making prerequisite dependencies.
