Isn't the host what you call target? When cross-compiling, the host machine
normally refers to the system where the built programs will be run, and
target machine to where the a compiler will run, in case a compiler is being
(cross-)compiled.

${MESON_HOST_ENDIAN} is used inside the [host_machine] statement, so this
looks right.

${MESON_TARGET_ENDIAN} is used inside a [target_machine] statement, though.
Not sure about the naming and intention here...
