Yes, but I added -pthread to LDFLAGS. Otherwise, configure uses the 
internal copy of libffi.

I think that configure should stop if "--enable-libffi" is used and 
configure's tests fail. The current behavior is a little weird because 
users usually don't read the output of the build process and configure 
is ignoring their options.

Look https://github.com/atgreen/libffi/blob/master/libffi.pc.in . By 
default, "pkg-config libffi --libs" will never return "-pthread".
