Dear Maintainer,

The package fails to build under various conditions,
including on both of the builders I care about.

If you have CAP_DAC_OVERRIDE (e.g. you're running the build as root), fs_chown fails:

[%  82|+ 161|-   0|T   0|S   1]: fs_chown
`fs_chown` failed: exit code 134
Output from process `fs_chown`:
Assertion failed in test/test-fs.c on line 200: req->result == -1
=============================================================


If you are running the build without public networking, the udp_multicast_* tests fail:

[%  31|+  59|-   2|T   0|S   1]: udp_multicast_join
`udp_multicast_join` failed: exit code 6
Output from process `udp_multicast_join`:
Assertion failed in test/test-udp-multicast-join.c on line 116: r == 0
=============================================================

[%  31|+  59|-   3|T   0|S   1]: udp_multicast_ttl
`udp_multicast_ttl` failed: exit code 6
Output from process `udp_multicast_ttl`:
Assertion failed in test/test-udp-multicast-ttl.c on line 47: status == 0
=============================================================
