I'm not sure off hand how to run an individual test to confirm, but
the testrun output up to the failure is:

  LINK  tests/spapr-phb-test
GTESTER check-qtest-aarch64
GTESTER check-qtest-alpha
GTESTER check-qtest-arm
GTESTER check-qtest-cris
GTESTER check-qtest-i386
blkdebug: Suspended request 'A'
blkdebug: Resuming request 'A'

GTester: last random seed: R02S181acd6574060796874e02dbdeb86199

Generally speaking I've only encountered build errors on FreeBSD, and
as long as it built the full test suite passed.

Yeah, it's almost certainly just exposing the existing failure.
