I don't think this is true for ET_DYN. Have you tested that? It's
not related to undefined symbols; it's caused by not linking an
ET_EXEC against any shared libraries.
This is solved by the --force-dynamic option in the VxWorks port of
ld. The feature was not desired for other targets so the option is
restricted to VxWorks.
