make cross fails due to libchill

Since none of the implementors seem to be forthcoming with a solution,
I've made my own workaround:

Thu Nov 19 20:39:18 1998  J"orn Rennecke <amylaar@cygnus.co.uk>

	* basicio.c (PATH_MAX): Define only to _POSIX_PATH_MAX if that is
	defined.  Otherwise, try MAXPATHLEN.
