# A setting that causes bootstrapping to occur using the `exec` config rather
# than the target config.
#
# The exec config is the more technically correct way of doing bootstrapping
# than the target config. For example it allows bootstrapping with a target that
# isn't compatible with the current execution host. However, in development
# builds, it is likely to force building the entire toolchain twice -- once in
# the target config for running test, and a second time in the exec config for
# the bootstrap. As a consequence, this is disabled by default.
#
# TODO: Add documentation for using the bootstrap flags once stabilized.
