Linus is right.  Quoting the documentation:

autotools:
--build: In which system the program will be built.
--host: In which system the generated program will run.

Meson:
build machine is the computer that is doing the actual compiling
host machine is the machine on which the compiled binary will run

So changing host_machine to use BUILD_* variables is wrong.
