From fb71372d5f59de5ae3eaece431fcfb007b264008 Mon Sep 17 00:00:00 2001 From: Thomas Petazzoni Date: Mon, 20 Mar 2017 21:36:54 +0100 Subject: [PATCH] support/testing: add toolchain tests This commit adds an initial toolchain test case, testing the ARM CodeSourcery toolchain, just checking that the proper sysroot is used, and that a minimal Linux system boots fine under Qemu.
