Also, the default Blackfin core in Buildroot is bf609, and there's no support for it in the upstream gcc, which causes a build failure when building uClibc-ng because -mcpu=bf609 is not valid. It looks like we will need to: 1/ Change the default Blackfin core to something that the internal toolchain backend support 2/ Make the internal toolchain backend only available if the selected Blackfin core is supported Could you work on this?
