>Description:
devel/libffi-3.0.9 fails to build on mips because of libffi change 
http://github.com/atgreen/libffi/commit/115ab36fceee69740a01ce49bc27e1908cc237b1
 which causes sgidefs.h, which does not exists on NetBSD, to be included in 
src/mips/ffitarget.h.
reverting this part of the change allows libffi to be built.
