I don't really understand the question. They're userspace tools, so
whether you need them in any particular context depends on what you're
doing there.

According to commit a657ce8f ("Add DTC release version information.")
it came from the Linux kernel... circa 2007. The kernel's probably
doing something entirely different nowadays.

That.. seems like a pretty serious limitation, given that more and
more packages are moving away from make.
But, in any case, I wasn't suggesting this as a practical workaround,
but more as a diagnostic. If it works with meson we can look closer
at what it's doing and maybe duplicate it with make.
