I got completely bashed in the first level, changed a lot since previous
version.
I had to add USE_NOBTCFI=Yes in my 11th gen Intel, otherwise I'll run
into a SIGILL from the coroutine lib. That lib comes from boost's
context so I did try to add some _CET_ENDBR in the same places that
boost uses it (at the beginning of each function in
subprojects/koishi/src/fcontext/asm/make_x86_64_sysv_elf_gas.S to be
precise), but ended up running into the following trace
Program terminated with signal SIGILL, Illegal instruction.
