This new package provides the host variant of the Meson Build System, an
open source build system meant to be both extremely fast, and as user
friendly as possible.

More precisely, Meson creates configuration files for the Ninja build
system.

Besides building Meson, it generates a configuration file
("$(HOST_DIR)/etc/meson/cross-compilation.conf") to be used when
cross-compiling a Meson-based project.

 * bump to version 0.41.2

And what about host packages that use meson?

Yeah, pretty confusing, isn't it? Buildroot is wrong here, but since
we've been wrong for almost two decades now, we can't really change...

I'd still suggest a little rephrasing:

    # Note: Buildroot's and Meson's terminologies differ about the meaning
    # of 'build', 'host' and 'target':
    # - Buildroot's 'host' is Meson's 'build'
    # - Buildroot's 'target' is Meson's 'host'

Good question. I don't know about host packages that may switch to
Meson. But, out of curiosity, I'll try with a dummy package to see how
it would behave.

Looks sensible to me.

This leads to the following entry in the cross-compilation.conf file
  cpu = '"cortex-a53"'
and a compile failure on a first try to enable meson build for gstreamer1
package. The following patch fixes the entry to
  cpu = 'cortex-a53'
which fixes the gstreamer1 meson based build for me:

Note: the next version of libinput (1.9.0) drops autotools support and
changed to using meson, see [1].
