OK, this file was pretty much completely wrong. I copied it from the SunOS version, but our shared libraries are not THAT much like SunOS. In NetBSD a.out shared libraries, trampoline stubs have _DYNAMIC+n as their symbol, so we can recognize them with strcmp. We may also need SKIP_TRAMPOLINE_CODE(pc) eventually, but doing that right takes machine dependent code to lookup what the _DYNAMIC stub jumps to. (gdb appears to work OK on a.out without SKIP_TRAMPOLINE_CODE)

No longer need to include solib.h here.
