Not sure what's not understood. IIUC you want to disable LTO when building gcc natively on Android? As LTO is considered a "language", disabling it by means of the support for targets or hosts to disable languages (by setting the shell variable unsupported_languages) seemed to make sense...though looking closer, I see the language configury is slightly fudged and needs some code moving to fix that, as e.g. lto-plugin conditionals and special lto handling have snuck in before the unsupported_languages processing. Bah. Never mind. brgds, H-P
