It isn't clear what error you got, but you might try looking at
supported build scripts.  crosstool-ng can build a bare metal compiler
for riscv.  There is also the riscv/riscv-gnu-toolchain project on
github that can build a bare metal compiler.  You could try looking at
these build scripts to see how they work.
