I prefer to have all documentation self-contained rather than relying on an external resource - we could put the information in the man page description for `--warn-ifunc-textrel`. As we already know when the glibc fix is available (upstream at least) we wouldn't have anything to keep up-to-date: we can simply describe the issue, the fixed glibc version, and note that the option will be removed in the future. Keeping track of which distros have which glibc versions seems like a lot of work.

That said, this issue doesn't affect the BSDs, so you ought to proceed with whatever is most natural/useful for Linux folks.



================
Comment at: docs/ld.lld.1:433
+Warn about usinc IFUNC symbols in conjunction with text relocations.
+This will cause segment faults if linked with glibc version 2.28 and before.
