Thanks Andrew.  This set of changes were already in libffi...

       * src/powerpc/ffitarget.h (ffi_abi): Add FFI_LINUX and
       FFI_LINUX_SOFT_FLOAT to the POWERPC_FREEBSD enum.
       Add note about flag bits used for FFI_SYSV_TYPE_SMALL_STRUCT.
       Adjust copyright notice.
       * src/powerpc/ffi.c: Add two new flags to indicate if we have one
       register or two register to use for FFI_SYSV structs.
       (ffi_prep_cif_machdep): Pass the right register flag introduced above.
       (ffi_closure_helper_SYSV): Fix the return type for
       FFI_SYSV_TYPE_SMALL_STRUCT. Comment.
       Adjust copyright notice.

       * configure.ac: Add amd64-*-freebsd* target.
       * configure: Regenerate.


The most difficult part of the merge is the configury, which is why I 
have been selectively cross merging for the past while.
