See Makefile.def. It specifies a host-gettext module that has the extra
flags set.
If the in-tree configuration is used, then the uninstalled-config.sh
gettext generates is used. See config/gettext-sister.m4.
gettext.m4 is unaltered, but it is essentially only used when the
gettext in-tree source is not present (because, otherwise,
gettext-runtime generates uninstalled-config.sh even if it builds
nothing)
Hope that answers it.
