Sure, where can I find this test suite?

It's a part of strace, you can find it e.g. at
https://github.com/strace/strace

To build and run it one can roughly do
./bootstrap && ./configure && make -j`nproc` && make -j`nproc check

make check produces some test failures on v6.14-rc1 on ARM
even before I apply the generic entry:

FAIL: filtering_syscall-syntax.test
FAIL: qual_fault-syscall.test
FAIL: qual_fault.test
FAIL: strace--tips-full.test
FAIL: strace-r.test

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

Then there is the fact that I had to add the  PTRACE_SYSEMU and
PTRACE_SYSEMU_SINGLESTEP as stubs returning -EIO
(modeled after UM) to use generic entry. Do you think this affects
the results?

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

Is there a way to run a single test? I tried to check the docs but
nothing obvious to me ... I guess I'm not used to this unit-tester.

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'
