The header search path -I. in kernel Makefiles is very suspicious; it allows the compiler to search for headers in the top of $(srctree), where obviously no header file exists.
-Iinclude/math-emu seems unnecessary because all files include headers in the form of #include <math-emu/...>. I was able to build without these header search paths.
