[Bug 286502] RTLD deadlocks during IFUNC resolution

I'm a little confused.

If the first symbol in foo.so to be resolved by _rtld_bind were just a regu=
lar
STT_FUNC, filter loading would happen there and no deadlock would occur when
the ifunc is resolved in the future.

So, the resolver does not inherently cause the filter loading, and deadlock=
 may
or may not happen depending on whether the resolver is the first resolved
symbol. This seems rather undesirable.
