[dpdk-dev] [PATCH v5 1/4] build: bump minimum Meson version to 0.47.1

[Luca Boccassi <bluca@debian.org>]

Meson 0.47.1 fixed a bug that is difficult to work around, which causes
the linker flag of dependencies to be repeated dozens of times, which
causes issues especially when using the built-in dependency() API.
Bump the minimum version and remove obsolete version checks.

v2: bump meson minimum version to 0.47.1 to avoid meson bug
v3: split away first independent patch from series
v4: add acked-by
