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

# The following is the list of directories which contain Makefiles with
# targets to install header file. The machine independent headers are
# installed by invoking the Makefile in the directory containing the
# header files. Machine and architecture dependent headers are installed
# by invoking the main makefile for that architecture/machine which,
# in turn, is responsible for invoking the Makefiles which install headers.
# It is done this way so as not to assume that all of the header files in
# the architecture/machine dependent subdirectories are in completely
# isomorphic locations.
