 AssertionError: False is not true

    squid test, as apache is configured to load
    /etc/ssl/certs/ssl-cert-snakeoil.pem in that test.

    This fixes the following error:
    make[1]: Leaving directory '/tmp/autopkgtest.jkIUNh/build.sNE/src/test-suite'
    make[1]: *** No rule to make target '../src/mem/libmem.la', needed by 'MemPoolTest'.  Stop.
