&gt; &gt; The others may need some love. Of course they're possibly because of my 
&gt; &gt; particular environment (Gentoo is a little bit different than "ordinary" 
&gt; &gt; distros like Debian/Fedora, and I already have to symlink the 
&gt; &gt; libgcc_s.so and libstdc++.so to pass the nptl tests at all)
&gt; 
&gt; I can tell tst-nss-files-hosts-long is most likely PR24816.  For the
&gt; others I'm not sure.
&gt; 
&gt; By "symlink libgcc_s.so and libstdc++.so" I guess you are running tests
&gt; in a temporary system ("Gentoo stage 1" IIRC).  In LFS we also get some
&gt; additional test failures in the temporary system [1] so it's better to
&gt; rerun the tests in a full system.
&gt; 
&gt; (In earlier LFS releases we also needed to symlink libgcc_s.so and
&gt; libstdc++.so for glibc tests, but it's no longer needed now thanks to a
&gt; major refactoring [2].)

&gt; [2]: https://lists.linuxfromscratch.org/sympa/arc/lfs-dev/2020-05/msg00000.html
&gt; 
&gt; My test result on LFS (fully built) with a patched ld seems clean.  The
&gt; patch is originally published at
&gt; https://sourceware.org/pipermail/binutils/2022-July/121852.html, but
&gt; it's in a large series introducing new relocation types.  I managed to
&gt; rebased and adjusted the patch so it can be applied individually for
&gt; binutils-gdb master branch.  The patch is attached in this mail.
&gt; 
&gt; +Zhensong: is there any possibility to merge this patch for binutils
&gt; master and 2.39 release branch (including 2.38 release branch would be
&gt; even better) so at least glibc ifunc tests will be happy?

This patch alone has not been fully tested， some ifunc implementations rely on new modifications.
If there is no problem with the tests, it can be merged into other branchs.
