1. miss debug info in assembly code
RISC-V-spike-htif_GCC
LDFLAGS add arch and abi info for linker
for riscv64-unknown-elf multilib, if there is no arch and abi
info, will link to default lib and have below error
target emulation `elf32-littleriscv' does not match `elf64-littleriscv'
use CFLAGS to replace ASFLAGS when compile assembly code
because DEBUG flag is added in CFLAGS, if we use ASFLAGS to compile
assembly code, there is no debug info in assembly code objfile
2. binutils 2.39 ld warn 'has a LOAD segment with RWX permissions'
RISC-V-Qemu-virt_GCC
RISC-V-spike-htif_GCC
RISC-V_RV32_QEMU_VIRT_GCC
3. fix build fail
RISC-V_RV32_QEMU_VIRT_GCC

* Put XLEN into .o files.
Makes it easier to work on voth RV32 and RV64 binaries side-by-side.
* Let the debugger disable HTIF use.
* Makefile now links the binary at BASE_ADDRESS
I need this so I can easily generate the appropriate binaries for
riscv-tests/debug. Unfortunately there doesn't seem to be any good
mechanism to externally define values for lds files, so I'm running it
through the C preprocessor.

* Add RISC-V demo for the spike simulator.
* Figuring out what the header checker wants.
* Fix more headers.
* Ignore htif.c and htif.h for header checks.
These files are already stamped with BSD-3-Clause, which I'm not allowed
to remove. There are numerous other files with the same license in
FreeRTOS, so I assume this is fine.
* Use proxy syscalls for RV32.
Looks like spike won't be changed to make htif character writes work
propery for RV32.
This is now an even closer copy of the version in opensbi, which is
arguably strictly better.
* Support RV64 builds to use with spike.
OpenOCD does not currently support debugging 64-bit FreeRTOS, but now
that I have a target to test hopefully that will be remedied shortly.
* Tweak rv32 instructions.
This way you can have separate cross-tools installations that can
coexist side by side.
