Temp workaround: use a single thread to generate native image

    Workaround for oracle/graal#1927

    Should be possible to remove this in 19.3.1

    This is a different problem to the previous one that this
    fix worked around, however because we were using this setting
    we only ran into the thread safety problem after it was removed.
