From d5997399b7ade650a7c894bf848a7e9463ae80e7 Mon Sep 17 00:00:00 2001 From: Jan Beulich Date: Fri, 3 Apr 2020 10:48:39 +0200 Subject: [PATCH] x86emul: suppress "not built" warning for test harness'es run targets The run* targets can be used to test whatever the tool chain is capable of building, as long as at least the main harness source file builds. Don't probe the tools chain, in particular to avoid issuing the warning, in this case. While looking into this I also noticed the wording of the respective comment isn't quite right, which therefore gets altered at the same time.
