[dpdk-dev] [PATCH] test-meson-builds: add 32-bit compilation test

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

Add in a cross-file to enable 32-bit compile tests as part
of the test-meson-builds script.

Signed-off-by: Bruce Richardson <bruce.richardson@intel.com>

NOTE: For ease of use, it's recommended that meson 0.47 be used for
this testing. With earlier versions, it may be necessary to ensure that
the same development packages are installed for both 64-bit and 32-bit.
