# Set up job pools for flang. Some of the flang sources take a lot of memory to
# compile, so allow users to limit the number of parallel flang jobs. This is
# useful for building flang alongside several other projects since you can use
# the maximum number of build jobs for the other projects while limiting the
# number of flang compile jobs.
