Build a linux image that boots on ariane
You need to have the riscv-gnu toolchain installed under $RISCV
. Both variants, newlib and libc, must be available.
If you want only softfloat the toolchain must be compiled with
../configure --prefix=/opt/riscv --with-arch=rv64imac --with-abi=lp64
make bbl
the restulting image should be in ./bbl
