From time to time, `7zip` invoked by `xaprepare` with an error similar to:

    ERROR: Dangerous symbolic link path was ignored : android-ndk-r26c/toolchains/llvm/prebuilt/linux-x86_64/lib/python3.10/site-packages/lldb/lldb-argdumper : ../../../../bin/lldb-argdumper
    ERROR: Dangerous symbolic link path was ignored : android-ndk-r26c/toolchains/llvm/prebuilt/linux-x86_64/lib/python3.10/site-packages/lldb/_lldb.cpython-310-x86_64-linux-gnu.so : ../../../liblldb.so

The problem is that this symlink is **not** a dangerous one, as it doesn't 
point outside the archived directory tree.

This happened on mac, Windows and Linux alike.

Try to work around the issue by using an undocumented `-snld` 7zip option 
when extracting ZIP archives.  Since the option is understood only from
`7-Zip` 20.x, check the version before using the argument.
