From 9a3f21fe5cb9f5654ccad7ba712d868f7de66e39 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Bj=C3=B6rn=20T=C3=B6pel?= Date: Mon, 9 Jan 2023 12:42:51 +0100 Subject: [PATCH] selftests: vm: enable cross-compilation MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Selftests vm builds break when doing cross-compilation. The Makefile MACHINE variable incorrectly picks upp the host machine architecture. If the CROSS_COMPILE variable is set, dig out the target host architecture from CROSS_COMPILE, instead of calling uname.
