Thanks for the report. I reproduce it with gnulib testdirs
$ rm -rf ../testdir1; ./gnulib-tool --create-testdir --dir=../testdir1
--single-configure canonicalize-lgpl
$ rm -rf ../testdir2; ./gnulib-tool --create-testdir --dir=../testdir2
--single-configure canonicalize
when run on Alpine Linux 3.9, 3.14, and 3.19.
History of these failures:
- For many years, one of the tests was failing on Alpine Linux.
- On 2021-01-17, I added a fix, that consists of a realpath() override [1].
- On 2022-07-31, the bug was reported again [2], against the sed-4.8 release
which predates the 2021-01-17 fix [3].
- On 2023-09-04, Paul changed the behaviour of the unit tests on musl libc,
without giving an explanation [4].
- Now, the unit tests fail again, as reported above.
I'm therefore partially reverting Paul's change from 2023-09-04 (attached).

I think you must ask this to yourself:
- What caused you to change the unit tests on 2023-09-04?
- How is the musl version that you used on that date configured?
What I use is Alpine Linux, as I said in versions 3.9, 3.14, 3.19.
- Did you work with gnulib testdirs at that time, or did you use
a package in which some modules are --avoid ed from import?
