There was a problem hiding this comment.
We could try conditionally linking against librt for glibc versions < 2.34.
But I think that not really necessary, and just complicates the BUILD files.
So the fix looks good from my point of view.
Address review feedback on eclipse-score#618: glibc 2.34 merged librt and libpthread into libc, but the explicit links stay for older glibc versions. Add a comment in the BUILD file so this is not rediscovered later. Signed-off-by: amelia@ivis.ai <amelia@ivis.ai>

The comment about glibc v2.34 folding libpthread/libdl/libutil/ libanl/librt into libc had a trailing space, which failed the Common PR checks formatting check. Signed-off-by: amelia@ivis.ai <amelia@ivis.ai> Signed-off-by: hskang <amelia@ivis.ai>
