	help
	    ARM 64 bit architecture
	    Note that individual mode will only work on machines
	    that provide floating point traps, which are optional on ARM.

	help
	    RISC-V 64 bit architecture with at least F and D
	    Note that individual mode will only work on a variant
	    of RISC-V ("RAFT-V") that includes floating point traps.

   help
      Prefix for all compilation tools (for cross-compilation use)
      "riscv64-unknown-linux-gnu-" is used for cross-compiling
      for riscv64, which is necessary for the RAFT-V setup

       Hardware support for floating point traps

       Use hardware support for Kernel-Bypass Exceptions (KBEs)
       to deliver floating point traps
       Not available in standard RISC-V, only RAFT-V
       The kernel module also needs to be inserted

         Use kernel module support for fast delivery of
