"--disable-darwin-at-rpath" causes the "loader_path" to be used instead of the "rpath" for finding libraries.
This allows to use the SDK without calling the relocate script which is changing the rpath values (LC_RPATH on MacOS).

Also add "Signed-off-by" line to aarch64-Darwin patch.

Before:
```
$ llvm-objdump -p ./sysroots/x86_64-pokysdk-darwin21/usr/bin/clang-18 | grep -A2 -i libstdc++
         name @loader_path/../lib/libstdc++.6.dylib (offset 24)
```

After:
```
$ llvm-objdump -p ./sysroots/x86_64-pokysdk-darwin21/usr/bin/clang-18 | grep -A2 libstdc++
         name @rpath/libstdc++.6.dylib (offset 24)
```
