Many tests used direct paths to some commands, mostly /bin/echo and /bin/cat. This is unportable (breaks on e.g. NixOS). The correct way is to obtain the direct path using 'whence -p'. There was also one use of '/usr/bin/pstack' in tests/comvario.sh that seemed bogus. Apparently this was supposed to analyse a core file after a crash. Even on Solaris and Linux, where that command exists, the argument is documented to be a PID, not a core file. If this ever worked anywhere, then it was system-specific enough to be useless here, so I've removed it. (cherry picked from commit 4563b8bc651cd9cb18dc73f56a041f7ac5534395)
