While the issue is real, this is not the reason while the package fails
to build from source. The test is marked as XFAIL as shown above.

Thanks for submitting the patch upstream. Given the above, I think it is
better to wait for an answer from upstream before applying it.

TIMEOUTFACTOR just increases the timeout, if you don't specify it, the
test will just fail faster.
