Hello David,

Do you still have any concerns about this change?
Do you have any similar use-cases that you can test? (i.e., check if pkg-config can detect a cross-built dependency for ppc64le).

By the way, we do a similar change for arm cross builds:
https://git.dpdk.org/dpdk/commit/config/arm/arm64_armv8_linux_gcc?id=f31d17807236094268ccd1bead5d740a10fec513

Thanks,
Ali
