From 2ddf7d3e8326e8cb07101ddb2d6e5dc6866371e2 Mon Sep 17 00:00:00 2001 From: Richard Purdie Date: Sun, 15 Apr 2012 18:05:53 +0100 Subject: gcc-configure-common.inc: Stop gcc looking at build system paths There were puzzling failures when you make a force recompile of any gcc component. The error was in do_configure with cross-compilation badness being detected in config.log files. gcc is different in that many of the config.log files are generated during the do_compile phase. This means this host contamination issue has always been present but only shows up on a rebuild. The fix is to force the appropriate configuration variable to "none required" then gcc won't look in the bad locations.
