Parallel build failure

- Subject: Parallel build failure
The script observer.sh uses a temporary file name that only depends on the
basename of the output file name. This can cause the two instances of
them to step on each other toes when observer.h and observer.inc are
built in parallel.
Tested on ia64-suse-linux with make -j20 and committed as obvious.
Andreas.

* observer.sh: Use different temporary file name depending on mode
of operation to avoid clash during parallel build.
