# Build with MVP CPU target, two reasons:
# 1. It is required for wasm2js support
# 2. While webpack supports it, it has some compatibility issues that lead to strange results
# Note that this requirest build-std which is an unstable feature,
# this normally requires a nightly build, but we can also use the
# RUSTC_BOOTSTRAP hack to use the same stable version as the normal build
