[dpdk-dev] [PATCH 1/2] build: fix kernel compile on cross-build

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

When cross-compiling, if no kernel_dir was specified, then the kernel
modules were still being compiled for the build machine. Fix this by
only building modules on cross-compile when we have a kernel_dir value
set.

Fixes: a52f4574f798 ("igb_uio: build with meson")
