Bug #3281: fail to build fiddle on Debian/lenny by default

Hi Aaron --

fiddle cannot be built on Debian/lenny by default, because extconf.rb
fails to find ffi.h.  It can be built by specifying the path:

  ./configure --with-libffi-include=/usr/include/i486-linux-gnu

But I think it should be built by default on Debian/lenny because it
is the supported platform.


The following patch works for me, but I don't know whether it works
on other platforms.

diff --git a/ext/fiddle/extconf.rb b/ext/fiddle/extconf.rb
