# @proj-tweak-default-env-dirs
#
# This function is not useful before [use system] is called to set up
# --prefix and friends.
#
# For certain target environments, if --prefix is _not_ passed in by
# the user, set the prefix to an environment-specific default. May
# emit output. For such environments its does [define prefix ...]  and
# [proj-opt-set prefix ...], but it does not process vars derived from
# the prefix, e.g. exec-prefix. To do so it is generally necessary,
# late in the config process (immediately before ".in" files are
# filtered) to also call proj-remap-autoconf-dir-vars.
#
# Returns 1 if it modifies the environment, else 0.
