README may be incorrect about vending XCHammer.app

[ndmeiri]

Hello! The README states that

Pinterest vendors XCHammer.app for reproducibility and simplicity.

But I cannot locate an official release of XCHammer.app in this repository. Some of the samples contain symlinks to xchammer.app, but I assume those aren't official. Does the README need to updated?

For context, I was trying to reference XCHammer.app/Contents/Resources in a Bazel repo rule to avoid having to install XCHammer via make install and instead download the binary on the fly when calling bazel build .... Is this approach possible and/or supported?

Thanks!

I am also looking into using xchammer in bazel without having to do make install. @jerrymarino could you maybe give us some guidance? 😄 Thanks!
