b390ced356 macho: specify -install_name as full dylib's name 
This then allows for proper resolution of names via runpath search
path list, i.e., `-rpath @loader_path` will correctly resolve
to `@rpath/libxxx.dylib (...)` in the linked binary.

c4853ba7ea Version-gate appending -syslibroot flag to lld 
This commit version-gates appending `-syslibroot` flag to lld. This
is predicated upon the fact that for versions of macOS lower than
11, lld would fail to find and link against frameworks with this
flag specified.

8eaaa905f7 stage2: Make zig cc more verbose (#7166) 
* stage2: Make zig cc more verbose

Make `zig cc` print more info from Clang itself and from our own linker
invocation, this is needed for CMake to properly discover all the
include directories and library search paths.

Closes #7110

* Update `update_clang_options`

* Typo fixes

e0e3ceac19 Re-enable system linker hack 
It is now possible to force linking with system linker `ld` instead
of the LLVM `lld` linker when building natively on the target. This
can be done at each stage by specifying `--system-linker-hack` flag,
and can be useful on platforms where `lld` fails to operate properly
such as macOS 11 Big Sur on ARM64 where every binary/dylib is expected
to be codesigned.

Some example invocations for each stage of compilation of Zig
toolchain:

```
cmake .. -DCMAKE_PREFIX_PATH=/path/to/llvm -DSYSTEM_LINKER_HACK=1
```

```
build/zig build test --system-linker-hack
```

```
build/zig build --prefix $(pwd)/stage2 -Denable-llvm
--system-linker-hack
```

```
build/zig build-exe hello.zig --system-linker-hack
```
