+Subject: kbuild: Use -nostdinc in compile tests
+Bug-Debian: https://bugs.debian.org/726861
+Bug-Debian: https://bugs.debian.org/717557
+Forwarded: https://marc.info/?l=linux-kbuild&m=141523555023625
+
+gcc 4.8 and later include <stdc-predef.h> by default.  In some
+versions of eglibc that includes <bits/predefs.h>, but that may be
+missing when building with a biarch compiler.  Also <stdc-predef.h>
+itself could be missing as we are only trying to build a kernel, not
+userland.
+
+The -nostdinc option disables this, though it isn't explicitly
+documented.  This option is already used when actually building
+the kernel, but not by cc-option and other tests.  This can result
+in silently miscompiling the kernel.
