From 52b952e474e655f8b4b6501813d57e20c9f02ba2 Mon Sep 17 00:00:00 2001 From: Daniel McGregor Date: Wed, 28 Sep 2022 16:13:19 -0600 Subject: gcc: set the default target arch The default x86-64 architecture for target gcc (ie, the one in poky build appliances) is native. Since we have a variety of build systems it will occasionally produce instructions that don't work on all of our development system. Instead, set gcc's default architecture to the one specified in TUNE_CC_ARCH, that guarantees that gcc-runtime and any binaries produced are compatible with the target machine type.
