[dpdk-dev] [PATCH] doc: fix build on Windows with meson 0.58

[Dmitry Kozlyuk]

The `doc` target used `echo` as its command.
On Windows, `echo` is always a shell built-in, there is no binary.
Starting from meson 0.58, `run_target()` always searches for command
executable and no longer accepts `echo` as such on Windows.
Replace plain `echo` with a Python one-liner.

Sorry for the noise, sent to stable@ instead of dev@ first.

One small suggestion might be to move the "echo" command definition to
buildtools folder in case it's wanted for use anywhere in the build at some
point in the future. However, this patch is fine without that change too.

I did the move in buildtools/meson.build:
echo = py3 + ['-c', 'import sys; print(*sys.argv[1:])']
