V8's Linux debug builds are not statically linked. The archived `d8` depends on `libv8.so` which is not included in the archive.

Reproduction steps:

    wget https://storage.googleapis.com/chromium-v8/official/canary/v8-linux64-dbg-7.0.237.zip
    unzip v8-linux64-dbg-7.0.237.zip
    ./d8

Expected result:

The `d8` shell opens

Actual result:

    ./d8: error while loading shared libraries: libv8.so: cannot open shared object file: No such file or directory
