[parisc-linux] make dep not working on HP-UX

[Ulrich.Strelow]

I have had a similar problem on our production HP-UX systems. Running ls *
on a directory with a lot of files gives
ksh: /usr/bin/ls: arg list too long

To solve this problem you need to set the HP-UX kernel parameter
large_ncargs_enabled  1
and rebuild the HP-UX kernel.

Here is the information from HP Electronic Support Center:

Problem Description

What is the impact of changing the kernel parameter
"large_ncargs_enabled" from 0 to 1?

What is the meaning of this parameter?

Configuration Info

Operating System - HPUX
Version-
Hardware System - HP 9000
Series -

Solution
When large_ncargs_enabled is set to "1", it increases the default
"environment size" (the memory set aside to be your login
environment - to hold your PATH variable, etc.) from 20478 to
2048000. SAM doesn't have any info about this parm or any max/minvalue.

If you have been having trouble using an "rm *" on really big
directories (it was running out of environment space), the command
will work when you set it to 1.  Regarding system performance, it
will eat up extra memory (2 M vs. 20 K), but if you don't have too
many users and you have plenty of RAM, it shouldn't be a problem.

Change the Makefile to use ./include instead of $(TOPDIR)/include for
the FINDPATH.  This shortens the arg list and make dep will work.
