ports/126518: Unbroke archivers/lzo2 on i386

[Matthias Andree]

Please close this PR. It is superseded by ports/130154, which is
supposed to fix the "lzo2 BROKEN" issue for good.

Please commit ports/130154 ASAP.

Christian Weisgerber figured out the self-test took ages because
malloc.conf contained J on some of the machines that took so long.
The PR mentioned above overrides said flag to accelerate the test.

Thanks
Matthias
