[Buildroot] [RFC] iputils (meson build system) has git version from buildroot instead of iputils

[Petr Vorel]

Hi all,

meson.build [1] uses git-version.h.meson [2] to produce BUILD_DIRECTORY/git-version.h.

Building from sources (not in Buildroot) it works:
$ head -1 builddir/git-version.h
#define PACKAGE_VERSION "20211215-15-g309f285"

But building in Buildroot it gets git version from Buildroot:
$ head -1 output/build/iputils-20211215/build/git-version.h
#define PACKAGE_VERSION "2022.02-876-g3ef096786a"

Is it a bug in iputils or in Buildroot meson?
Any idea how to fix it?

Kind regards,
Petr
