This sounds eerily similar to port-macppc/54827 - there's quite a bit
of confusion early on on my part there, but scroll to the last couple
of mails.  http://gnats.netbsd.org/54827

It looks like some logic changed in MI gcc8 that broke netbsd MD
config headers and I wonder if you see the same problem here.  For
macppc the fix was also to undo the netbsd change to STACK_BOUNDARY in
favor of PREFERRED_STACK_BOUNDARY.

May be we should also check other ports for similar gotcha proactively?
