This patch extends gABI with DT_FLAGS_2 and DF_2_GNU_IFUNC to indicate

I don't think this will solve any of the thorny cases. It may help with
missing DT_NEEDED entries, but that's only a small subset of the issues, and
as far as linking against glibc is concerned, such binaries are invalid
anyway.
In my case, LD_PRELOADed shared library is linked against libc.so. But there
is no dependency on it by definition.
