[dpdk-dev] [PATCH v2] net/bnx2x: fix meson build failure

[Rasesh Mody]

Use kernel headers for __le* types to avoid potential conflicts
resulting in redefinition errors for Linux build environments.
Add check for FreeBSD execution environments.

Without this fix, aarch64 builds can fail with error [1] below.

Fixes: 38dff79ba736 ("net/bnx2x: update HSI")

v2:
  Use RTE_EXEC_ENV_FREEBSD in place of __FreeBSD__
