def spawn_nofetch(portdb, ebuild_path, settings=None):
This spawns pkg_nofetch if appropriate. The settings parameter
is useful only if setcpv has already been called in order
to cache metadata. It will be cloned internally, in order to
prevent any changes from interfering with the calling code.
If settings is None then a suitable config instance will be
acquired from the given portdbapi instance.
A private PORTAGE_BUILDDIR will be created and cleaned up, in
order to avoid any interference with any other processes.
If PORTAGE_TMPDIR is writable, that will be used, otherwise
the default directory for the tempfile module will be used.
We only call the pkg_nofetch phase if either RESTRICT=fetch
is set or the package has explicitly overridden the default
pkg_nofetch implementation. This allows specialized messages
to be displayed for problematic packages even though they do
not set RESTRICT=fetch (bug #336499).
This function does nothing if the PORTAGE_PARALLEL_FETCHONLY
variable is set in the config instance.

settings = config(clone=portdb.settings)

# doebuild_environment(), since lots of variables such
