This patch extends gABI with DT_FLAGS_2 and DF_2_GNU_IFUNC to indicate
that a shared object or executable has IFUNC symbols so that dynamic
linker can relocate it early.

I don't think this will solve any of the thorny cases. It may help withmissing DT_NEEDED entries, but that's only a small subset of the issues,and as far as linking against glibc is concerned, such binaries areinvalid anyway.


Thanks,
