Which are you trying to fix? The on target gcc or the SDK one? In the SDK case, we have environment files which do explicitly specify the compiler flags. On target is harder however the on target gcc is compiled to a specific PACKAGE_ARCH so we should be able to put specific tuning into that gcc. It does sound like the changes to gcc-configure-common.inc were not the way to resolve this though, I'd misunderstood what the patches were doing. Can we fix this by adjusting gcc itself (the on target version)? Its even a very old bug: https://bugzilla.yoctoproject.org/show_bug.cgi?id=139 but we've not actually hit issues due to this before or at least they've not been reported in these terms.
