[PATCH] Multi-arch SKIP_SOLIB_RESOLVER

[Mark Kettenis <kettenis@chello.nl>]

I'm working on integrating some mostly SPARC-related patches from
David S. Miller.  There were also some general bits in his tree that
I'm going to check in on mainline.  Here's the first.

Committed as obvious (to mainline).
