It looks portable to me (as long as you don't expect your
assignment to hold for the submakes of the one being launched,
of course, but that's not needed here).

"Update." :)

Somme comment along the lines of 
## Disable am__remove_distdir so that sub-package do not clear a

## populated (e.g. shared AUX dir in the sub-package.)
maybe ?  At least it sure would help my bad memories.

Otherwise the patch looks fine to me, please install!


+cat >subpkg/foobar <<'END'
+foobar

+cat >subpkg/Makefile.am <<'END'
+SUBDIRS =

It doesn't matter to me here, but those could be echos if you care
for speed (I think to remember you do).
