doc: fix Linux guide for arm64 cross-compilation

libnuma.so is needed to augment the cross toolchain with NUMA support.
This fixed meson cross compiling issue.

Command used:
meson arm64-build --cross-file config/arm/arm64_armv8_linux_gcc
ninja -C arm64-build

Compiling error:
.../aarch64-linux-gnu/bin/ld: lib/librte_eal.so.10.1: version node
not found for symbol numa_run_on_node_mask@@libnuma_1.2
.../aarch64-linux-gnu/bin/ld: failed to set dynamic section sizes:
