With TEST_HOST it tests just the command name, however the shell decides to
resolve that. Without that it tests the path to the toybox command.

Instead you want the TEST_HOST version also to not test the shell builtin? (Some
host systems don't have non-builtin versions of things like "echo". It's a
design question of what counts as the "host version"...)
