deps: cherry-pick e020aae394 from V8 upstream

Original commit message:

    Work around glibc thread-local storage bug

    glibc before 2.17 has a bug that makes it impossible to execute
    binaries that have single-byte thread-local variables:

        % node --version
        node: error while loading shared libraries: cannot allocate
        memory in static TLS block

    Work around that by making the one instance in the V8 code base
    an int.
