Is building as ET_DYN supported upstream? We previously had reports of
building system of some distros to be plainly borked and usualy the
distro fixed their building system pretty fast. If upstream supports
ET_DYN, then this patch is accepted with no further questions. But if
it's a borked building system it may have subtle bugs and allowing it
would probably just suppress an early symptom of other problems.
