# The cross file logic is similar but not identical to that in meson.bbclass,
# since it's generating for an SDK rather than a cross-compile. Important
# differences are:
# - We can't set vars like CC, CXX, etc. yet because they will be filled in with
#   real paths by meson-setup.sh when the SDK is extracted.
# - Some overrides aren't needed, since the SDK injects paths that take care of
#   them.
