Would it be reasonable to make RUNTIME_PREFIX the default on systems where we _do_ have that support? AFAIK there is no downside to having it enabled (minus a few syscalls to find the prefix, I suppose, but I assume that's negligible).

I.e., a patch to config.mak.uname (and possibly better support for _disabling_ it, though I think "make RUNTIME_PREFIX=" would probably work).
