Yes, that's the plan.  I've noticed that the framework's improved
significantly over the years and I've been able to drop some of my
local hacks.

Any pointers for how to handle --disable-assembly configure option?
For instance, since libreswan requires libgmp, it would have:
   select LIB_LIBGMP
but libreswan doesn't know if --disable-assembly is required, that
would be set by a vendor/platform files?
