+Subject: [PATCH 2/3] At least try building for other archs than x86*
+
+Allow attempting to build for other architectures than x86 and x86_64,
+whether or not the build will succeed or produce sane output is another
+question... It emits plenty of warnings about it now though...
+
+Configuration of the FPU controller is disabled on all but x86*, and the
+uninformed hope and prayer is that defaults will be fine without messing
+with them.
