It looks like some bot attached to Jenkins CI. Not bogus, but it doesn't
seem working as intended. One of the emails has useful failure messages:

    Testing f64_rem.
    46464 tests total.
    Errors found in f64_rem:

One of the other emails shows the following:

    3a9fb97caf   Wilco Dijkstra   benchtests: Add random strlen benchmark

    42aba91895   Andreas K. Hüttel   Increase version to 2.41.9000, add new section to NEWS
    
So, I suspect it is emailing all patch authors (and maybe others?) since
the following commit:

    commit 42aba9189557280ad367c35908cbdfe26f5aeeb1 (tag: glibc-2.41.9000)

        Increase version to 2.41.9000, add new section to NEWS
        
        Signed-off-by: Andreas K. Hüttel <dilfridge@gentoo.org>

Which feels a bit more noisy than necessary.
