(Debug builds have --enable-slow-asserts, and with slow asserts each
assignment to the array in the prepare function will trigger a check
over the entire array. This turns it into n^2 work, for reasonably

The generated snapshot just crashes on the device, but
disabling snapshots allows us to run V8 just fine which
is sufficient for our purposes at this point.

Mojo/Sky are GN-only so we depend on the V8 GN build even if

The logic was supposed to trigger a rebuild if the CXX variable is
changed. However, it failed to track the other compiler related
variables, and, what is worse, conflicted with the clang=1 gyp setting
by forcing CXX to g++

The new logic just relies on tracking GYP defines, and checks whether
the CXX binary - if set - has a target different from the host
architecture.
