    sysutils/opensbi: fix build with clang 17
    
    Building sysutils/opensbi with clang 17 results in the following errors:
    
      clang: error: unsupported option '-mno-unaligned-access' for target 'riscv64-unknown-elf'
      clang: error: unsupported option '-mno-unaligned-access' for target 'riscv64-unknown-elf'
      [... many more times...]
    
    The target-specific option -mno-unaligned-access (which is emitted from
    the compiler driver when -mstrict-align is used) did not do anything for
    riscv64, but clang 17 is now more strict about reporting unsupported
    options. Remove the -mstrict-align option from the Makefile's CFLAGS and
    ASFLAGS to fix it.
