I have no idea! This time I did ...

make -j check

... but I often do ...

make -j 10 check

... so I repeated ...

make -j 10 check

... a few times thinking maybe another test could delete the link, but
could not reproduce the error. BTW, from each 'make check' I do end up
with a dangling link like ...

t-profile-alt-10987-1-link ->
/home/g1/src/guix/test-tmp/store/hwr4xiqd60wrh033wvjljly50j6d39dg-profile

... is this normal?

It is not reproducible ... except by deleting the profile while the test is
running ;-)
