Well this compiler was written to build Linux as a proof of concept. You don't need a libc for building the kernel. Was it claimed anywhere that it is a fully compliant C compiler?

That's kind of moving the goal post no? They set out to build a C compiler that could compile the kernel, it can do that just fine?
Searching for "compliant" in the README doesn't seem to indicate that building a "conformant compiler" was even the goal here, so not sure why that's suddenly should be a requirement.
The location of Standard C headers do not need to be supplied to a conformant compiler.

This is not a good implementation decision for a compiler which is not the C compiler distributed with the OS. Even though Standard C headers have well-defined names and public contracts, how they are defined is very much compiler specific.
So this defect is a "somethingburger."
