Change the symbol lookup order to search RTLD_GLOBAL objects
...
before referencing object's DAG. This makes it possible for
C++ exceptions to work across shared libraries.
Patch taken from FreeBSD: src/libexec/rtld-elf/rtld.c: 1.67 -> 1.68,
committed there by kan@FreeBSD.org .

Rework how MAKEVERBOSE operates:
...
* Don't bother prefixing commands with a line of ${_MKCMD}\
and instead rely upon "make -s". This is less intrusive on
all the Makefiles than the former. Idea from David Laight.
* Rename the variables use to print messages. The scheme now is:
_MKMSG_FOO Run _MKMSG 'foo'
_MKTARGET_FOO Run _MKMSG_FOO ${.TARGET}
From discussion with Alistair Crooks.

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.
