@shimamoto @takezoe this does not support all the pio build options and so
will not work if pio is built in a different way from this template. We need to
document this at very least and solve the pio vs template mismatched options
more fundamentally maybe by creating a sample template build that supports all
`make-distribution` options. But I see problems with doing this too so not sure
how to solve it.
