So far, I seem to be able to control those features on a build level
through CMake.

Fuchsia appears to need to be a port in the sense of having an
OptionsFuchsia.cmake in order to set the target triple to
x86_64-unknown-fuchsia.  I didn't find any other uses of
CMAKE_CXX_COMPILER_TARGET in WebKit.  Is there some other mechanism
folks use to set the target triple (or maybe other folks aren't
crosscompiling using clang)?

That sounds like a good approach to start with.  If we run into
trouble, we might need to adjust.
