And std::format shit is an absolute log4j vuln but wg21 wastes time on this
instead of fixing iostream.
LOL.
We see wg21 as a joke.

there is another stuff mentioned in osdev. we need to disable red zone. we need
redzone multilib

malloc, free, memset does not exist either.
Need to replace them with __builtin_malloc, __builtin_free, __builtin_memset if
that is available.
Then it is libquadmath's issue. no errno.h

These tests are very wrong tbh. freestanding environment of course, does not
have those

Oh, woops, my bad. This is for configuring and building GCC. I'm not sure which

The funny stuff is that __STDC_HOSTED__ should not be set as true. I guess GCC
incorrectly mark __STDC_HOSTED__ as 1 for C++, even we live in freestanding
environment.
