Build fails in v8 bindings

[Luka-Filipovic]

I'm always getting the same error while trying to build uc.
Ninja updated to latest
python 2.7.18, 3.9
llvm/clang 11.0 (tried with 12.0 with no success)
xcode 12.0.1.
I even tried with windows build but its the same error.

After all dependencies update, I'm no longer getting this error
