Our libffi exclusions in genrandconfig are really when there is no
support for a given CPU architecture in libffi.

In the situation we're talking about, libffi does have support for
RISC-V 64-bit. The limitation is not in libffi, but in uClibc-ng.

We could certainly have handled that by an autobuilder exception, but
I've never been a big fan of such autobuilder exceptions. That being
said, if the general feeling is that an autobuilder exception is a
better way of avoiding those build failures, I'm fine with changing to
that solution.

Best regards,

Thomas
