fix build on Hurd which doesn't define PATH_MAX
Hurd doesn't define PATH_MAX but is needed by pre-process.c
Allow sparse to build on Hurd by giving it a default value
of 4096.
Note: this solution is not ideal because *if* the path is
longer than PATH_MAX (and this *can* also happen on
non-hurd machine) then we have a nice buffer flow
which will corrupt the stack.
A better solution will come later.
