Hurd doesn't define PATH_MAX but is needed by pre-process.c
and sindex.c.

pre-process.c had already its local define but sindex doesn't.
So, allow sindex to build on Hurd and avoid possible problems
with some future tools by moving the default define of 4096
for it to lib.h where it will be visible for all code.
