Set PATH_MAX on systems without a default value
Some systems (HURD) use fully-dynamic pathnames, with no limit.
We can't support this without significant effort so for now set
PATH_MAX to a large value.
* src/makeint.h: Set PATH_MAX to 4096 if not set and MAXPATHLEN
is also not set. Remove MAXPATHLEN setting: we won't use it.
* src/misc.c (get_path_max): If we can't get the path max via
pathconf() use the default PATH_MAX.
* src/dir.c (find_directory) [W32]: Use MAX_PATH not MAXPATHLEN.
(local_stat) [W32]: Ditto.
* src/job.c (create_batch_file) [W32]: Ditto.
* src/remake.c (name_mtime) [W32]: Ditto.
* src/w32/w32os.c (os_anontmp) [W32]: Ditto.
