Following up on this part seperately. This is perfectly reproducible
when run from within Jenkins. This is what's used to execute make
syntax-check:

    make syntax-check

Which Jenkins simply puts into a script and consumes it's output

    /bin/sh -xe /tmp/hudson4405079863801767625.sh

Note that /bin/sh is dash in this case.
