Directories named by -I are searched before the
standard system include directories. Therefore a flag
like -I/path/to/kernel/headers shall suffice, isn't it?

Anyway, I tried adding -nostdinc but it breaks the
compilation of my kernel modules:

/usr/src/linux/include/linux/kernel.h:10:
  stdarg.h: No such file or directory

stdarg.h is a compilation header (not part of the kernel tree)
and -nostdinc tells the compiler not to look for the standard
include locations so it can't find it.

So either I use -I/path/to/stdarg.h or not use -nostdinc. Any
other options?
