The FreeBSD port for libffi is not marked as broken on amd64.  I'd be  
very surprised if libffi worked on x86-64 Linux but not FreeBSD, since  
they use exactly the same calling convention on this architecture  
(Linux uses PCC-compatible on-stack small-structure returns while  
FreeBSD returns them in register, and a few other minor differences on  
i386, but in 64-bit mode they are the same).

Would it be possible for you to check whether GNUstep works with  
libffi?  On FreeBSD/i386, it defaults to using ffcall, but works  
better with libffi (i.e. doesn't randomly corrupt the stack when you  
pass NSInvocations between threads).  You probably need to explicitly  
specify /usr/local/include and /usr/local/lib as ffi lib/include  
directories in configure.
