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.
