This is a pretty crazy "linux".  Not sure I would invest too much into
supporting such misfeatures myself.

A better solution may be to add a "sysdep" dir to libopenswan where strange
OS's can hide this junk :-)

Attached is a LGPL popen implementation that could be used if you wanted to go
that route (it even works on uClinux without an MMU).
