Do I just need a suitable sym link in my target fs or is this something wrong with how things are being built. Could it be that the toolchain wrapper is somehow forcing soft float?
If BR2_SOFT_FLOAT is set, the toolchain wrapper adds "-msoft-float" by default. But this option is only available if you build the toolchain with buildroot (or deprecated ct-ng backend)
