Module Name:    src

Modified Files:
        src/lib/csu/common_elf [netbsd-1-6]: common.h

Log Message:
Pull up revision 1.9 (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.
