From: Peter Feiner <pfeiner@xxxxxxxxxx> kvm-unit-tests builds with the odd combination of system include files but not system libraries. That is, -nostdlib is specified but -nostdinc isn't! Problems arise when the include files don't match the libraries, e.g., printf() in some versions of glibc linking in a __printf_chk symbol that libcflat doesn't have. This patch fixes the problem with printf by pointing '#include "stdio.h"' to lib/libcflat.h, where a printf declaration that libcflat actually implements exists, rather than letting /usr/include/stdio.h get included. This patch does not solve the general problem of potential mismatches between libcflat and the compiler's notion standard include files; doing so would require rewriting stdarg.h, stdint.h, and several others in libcflat.
