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.

__syscall takes a quad_t as its first argument, not an int.
...
_strrchr takes an int (due to promotion) as its third arg.
don't print the null byte at the end of string.
error messages should end with a linefeed.
