From 7f58b487e9ff3ff0f5f29a57172295a41f08a6b5 Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Wed, 1 Jul 2020 00:06:25 +0900 Subject: kbuild: make Clang build userprogs for target architecture Programs added 'userprogs' should be compiled for the target architecture i.e. the same architecture as the kernel. GCC does this correctly since the target architecture is implied by the toolchain prefix. Clang builds userspace programs always for the host architecture because the target triple is currently missing. Fix this.
