Add support for building kernels with clang. Clang does not support
-mno-fpu, so use -msoft-float instead. As long as we do not explicitly
use floating-point arithmetic in the kernel that probably has the same effect.
Add -Wno-unused-command-line-argument to prevent warnings that turn into
errors passing -Wa,-Av9b when we run genassym.sh.
