#
# DESCRIPTION
#
# This file defines the libraries, runtimes, and build rules needed to
# create executables from your Linux workstation that'll run anywhere.
# Loading this package will make certain systemic modifications to the
# build like turning off the System V "Red Zone" optimization, because
# αcτµαlly pδrταblε εxεcµταblεs need to be able to run in kernelspace.
