| Original patch from gentoo: gentoo/src/patchsets/gcc/4.3.1/gentoo/53_all_gcc4-superh-default-multilib.patch |
| The gcc-3.x toolchains would contain all the targets by default. With gcc-4, |
| you have to actually list out the multilibs you want or you will end up with |
| just one when using targets like 'sh4-linux-gnu'. |
| |
| The resulting toolchain can't even build a kernel as the kernel needs to build |
| with the nofpu flag to be sure that no fpu ops are generated. |
| |
| Here we restore the gcc-3.x behavior; the additional overhead of building all |
| of these multilibs by default is negligible. |
