Fails to build on several Debian architectures (s390x, alpha, hppa, powerpc, ppc64, sparc64) due to failing tests.

Hi,

Wireplumber fails to build on several Debian architectures (s390x, alpha, hppa, powerpc, ppc64, sparc64) due to failing tests. Not sure, if it's expected to work. See logs at https://buildd.debian.org/status/package.php?p=wireplumber&suite=sid

It's mainly due to these tests:

 5/22 test-object-manager    FAIL           0.60s (killed by signal 6 SIGABRT)
 7/22 test-proxy             FAIL           2.13s (killed by signal 6 SIGABRT)
 9/22 test-spa-pod           FAIL           0.33s (killed by signal 6 SIGABRT)
14/22 test-lua-pod           FAIL           2.94s (killed by signal 6 SIGABRT)
15/22 test-lua-monitor-rules FAIL           2.93s (killed by signal 6 SIGABRT)
19/22 test-si-node           FAIL           2.96s (killed by signal 5 SIGTRAP)
20/22 test-si-audio-adapter  FAIL           2.86s (killed by signal 5 SIGTRAP)
21/22 test-si-audio-endpoint FAIL           3.04s (killed by signal 6 SIGABRT)
22/22 test-si-standard-link  FAIL           2.98s (killed by signal 5 SIGTRAP)

Best,

Dylan
