p5.34-ffi-platypus @2.100.0 has problem with strnlib

[ballapete (Peter "Pete" Dyballa)]

On (PPC) Leopard, Mac OS X 10.5.8, when buildstarts Apple's crash log handler opens a window explaining something like

 Dyld Error Message:
  Symbol not found: _strnlen
    Referenced from: /opt/local/var/macports/build/_Users_ctest_perll_p5-ffi-platypus/p5.34-ffi-platypus/work/FFI-Platypus-2.10/.tmp/ffi-probe-sWrLNQ/libeval81.dylib
      Expected in: dynamic lookup

This can be overcome with a patch like this one:

– after the configure phase. Because Perl modules do not enjoy Legacy_Support, somethings else is needed.
