There is, apologies for missing it!

configure output looks fine.  Only issue was that the dev env uses
busybox which has built-in "uname", so I had to tweak configure to
know about that.  

The micro-problem is that ffitarget.h #defines FFI_CLOSURES to 0 and
so a ffi_closure struct isn't defined, yet unconditionally used by foreign.c
