description:
After a careful review, and all things considered, disable compat43 by
default on amd64. The use case is limited, the potential for damage too
high, and it is safer to run a BSD4.3 binary on i386 since the kernel does
not have to go through netbsd32 - which may not correctly reproduce i386.
