Subject[RFC 0/2] __vdso_findsym
Date
The idea is to add AT_VDSO_FINDSYM pointing at __vdso_findsym.  This
implements __vdso_findsym.

This would make it easier for runtimes that don't otherwise implement
ELF loaders to use the vdso.

Thoughts?

If people like the basic concept, I'll finish it, write up
documentation and a selftest. If people don't like it, I'll drop it.
