## NOTES:
## The tools/*-directories situation is unclear
## * tools/build are host-native tools to be installed on the host.
## * tools/cpu are host-native or host-cross-target-tools
## * tools/update are build-host-native tools
# these tools are built for the build environment
#
build_tools="tools/update"
# these libraries are built for the host environment
#
host_libs=""
# these tools are built for the host environment
#
host_tools="tools/build tools/cpu"
# these libraries are built for the target environment, and are built after
# the host libraries and the host tools (which may be a cross compiler)
#
target_libs="c"
# these tools are built using the target libs, and are intended to run only
# in the target environment
#
target_tools=""
## All tools belong in one of the five categories, and are assigned above.
## ${host_configdirs} is directories we build using the host tools.
## ${target_configdirs} is directories we build using the target tools.
