Subject: [PATCH] treewide: meson.build: use `host_machine` instead of
 `build_machine`

At the moment, cross compilation may not work in certain cases because
checks are carried out against the build machine instead of the host machine.
Replace uses of `build_machine` with `host_machine` to fix that.

In native compilation, all three "machine objects" available in meson
are the same, so this change should have no effect in that case.
