[dpdk-dev] [PATCH 4/7] build: disable pointer to int conversion warnings for 32-bit

[Bruce Richardson <bruce.richardson@intel.com>]

Converting a 32-bit pointer to a 64-bit integer is generally safe, but
generates a lot of warnings when compiling 32-bit code with meson. The
warnings are not flagged when using make, so just disable them for
32-bit meson builds.
