Recently, some distros have started shipping versions of gcc which default to -march=i686. This breaks building kernels for pre-i686 machines, even if they have been selected in Kconfig, due to the generation of CMOV instructions. There isn't enough benefit to try to preserve the generation of these instructions even when selected, so simply force -march=i386 for the decompressor when building a 32-bit kernel.
