$NetBSD: patch-extern_lzma_CpuArch.c,v 1.1 2025/06/02 00:29:09 mrg Exp $

Copy of textproc/ugrep/patches/patch-lzma_C_CpuArch.c:

Fix build on non-Linux arm32/aarch64 platforms. Especially on NetBSD the
kernel currently only provides information about optional CPU features to
userland via /proc/cpuinfo. Providing AT_SUN_HWCAP via auxv would be
nice. Adding getauxval(3) to crt would also be nice.
