    gnu: file-boot0: Fix building on riscv64-linux.
    
    * gnu/packages/commencement.scm (file)[configure-flags]: When building
    for riscv64-linux disable the use of xz.
    (file-boot0)[arguments]: When building for riscv64-linux adjust the
    make-flags to pass a different CFLAG to build for C11.
