Just released make 4.4 issues this prior to running the rules:

rt_sigaction(SIGPIPE, {sa_handler=SIG_IGN, sa_mask=[PIPE],
sa_flags=SA_RESTORER|SA_RESTART, sa_restorer=0x7ff547edbaf0},
{sa_handler=SIG_DFL, sa_mask=[], sa_flags=0}, 8) = 0

The attached patch (against m4 1.4.19) restores the default handler prior to
running the tests which allows them to pass.
