Subject: [PATCH] configure: add option for ps

The configure searches hardcoded host paths for PSPATH
and run ps commands to decide PSARG which will fail
on host without ps:
| configure: error: Cannot find ps in any of /usr/ucb /bin /usr/bin

So add an option so we can specify the ps at configure
to avoid host contamination.

Upstream-Status: Inappropriate [cross compile specific]
