# here as needed.
#
# WHAT GOES HERE?
#
# Other than the main compiler and linker configs, the only reason for a config
# to be in this list is if some targets need to explicitly override that config
# by removing it. This is how targets opt-out of flags. If you don't have that
# requirement and just need to add a config everywhere, reference it as a
# sub-config of an existing one, most commonly the main "compiler" one.
