# MAKE_ARGS - Any extra arguments to sub-make in build and install stages.
# Default: none
##
# MAKE_JOBS_SAFE
# - This port can safely be built on multiple cpus in parallel.
# The make will be invoked with -jX parameter where X equals
# number of cores present in the system.
# MAKE_JOBS_UNSAFE
# - Disallow multiple jobs even when user set a global override.
# To be used with known bad ports.
# DISABLE_MAKE_JOBS
# - Set to disable the multiple jobs feature. User settable.
# FORCE_MAKE_JOBS
# - Force all ports to be built with multiple jobs, except ports
# that are explicitly marked MAKE_JOBS_UNSAFE. User settable.
# MAKE_JOBS_NUMBER
# - Override the number of make jobs to be used. User settable.
# MAKE_JOBS_NUMBER_LIMIT
# - Set a limit for maximum number of make jobs allowed to be
# used.
