	src/lib/libc/dlfcn [netbsd-1-6]: dlfcn_elf.c

Log Message:
Pull up revision 1.4 (requested by skrll in ticket #1702):
Resolve dlsym(3) and friends directly so that dlsym(RTLD_NEXT,...) works.
Previously dlsym resolved to the version in crt0.o or libc which would
mean that the caller's shared object couldn't be determined correctly
using __builtin_return_address(0).
Mainly from FreeBSD, but adapted by me. Benefits of this solutions are:
	- backward comptibility maintained
	- existing broken binaries are fixed with a new ld.elf_so
	- __mainprog_obj can be removed from crt0.o
	- we do the same thing as FreeBSD
Fixes PR 22067.
OKed by Jason and Christos.
