Commit fix sent by Tor Egge <Tor.Egge@cvsup.no.freebsd.org>

Only use return value from system call if system call succeeded.

Tested with `make world` and some of my own scripts.

This should be MFCed soon.  While /bin/sh is hard to test the fix is
obviously correct and can be assumed not to break something else
(famous last words...).
