This is surprising, no tests are currently known to fail on arm.

No, strace doesn't use PTRACE_SYSEMU* and doesn't test it either.

Sure, it's a regular automake-based test suite, so you can do something like
$ make -s -k check VERBOSE=1 TESTS='filtering_syscall-syntax.test qual_fault-syscall.test qual_fault.test'
