For some reason, I don't see this in my configure.in.  Was this added
by the Debian patch?  In principle, it's a good idea to check for this
macro, but I the check needs to be different.  To get it to compile,
FFI_STATIC_CLOSURE() would have to be declared at the outermost level.
Alternatively, perhaps you can just grep for this macro in ffi.h (I
think autoconf has support for doing this).

PS: I dropped binutils from the cc list, as it's clearly not a binutils
    issue.
