[dpdk-dev] [PATCH v5 09/17] bus/dpaa: fix 64-bit arch detection

From: Natanael Copa <ncopa at alpinelinux.org>

There is no standard saying that __WORDSIZE should be be defined or in
what include it should be defined. Use RTE_ARCH_64 instead.

This solves a warning when building with musl libc:

 warning: "__WORDSIZE" is not defined, evaluates to 0 [-Wundef]

Fixes: 847ee3bd0d1f ("bus/dpaa: support FMAN frame queue lookup")
