I've been testing this and stuck in a few fixes. My changes are at git://repo.or.cz/buildroot-gz.git Fixes are various: * Fix mpc download site * Forward-port the powerpc softfloat patch (you probably didn't hit the problem because it's conditional) * Disable targetopts for powerpc and gcc 4.5.x * Fix a ton of ARM issues Word of caution, gcc 4.5 isn't able to build good ARM kernels that can load modules for versions <2.6.36 unless a patch is applied, see https://bugzilla.kernel.org/show_bug.cgi?id=16310 Tested for arm softfloat (hardware), arm hardfloat (qemu), mips32 (qemu), powerpc hardfloat (e300c3) and powerpc softfloat (qemu). Thanks for your work on this. Regards.
