#   1. Cross-compiling with no built compiler: Should work the same as
#      IREE_BUILD_COMPILER=OFF in a host build (i.e. nothing depending
#      on the compiler should be built).
#   2. Cross-compiling with a compiler built for the target: Anything
#      on the host which needs the compiler, still must have host tools.
#   3. Normal host build.
# This simplistic setup makes #2 impossible and it overloads #1 to
# also support building things that depend on the compiler. The targets
# need to be aliased/forked for host variants to fully support. For now
# we just make all of these as OPTIONAL and let things break if not set up
