+From: Gordon Malm <gengor@gentoo.org>
+
+Make distcc client pass -D__KERNEL__ macro. Hardened GCC uses this
+macro to determine if code intended to be run in-kernel is being compiled.
+If the code is kernel code, certain compile flags are not applied.
+
+When using distcc to build kernel code (modules, etc.) without this patch,
+the distccd host doesn't get passed -D__KERNEL__. Consequently, gcc on
+the distccd host applies all kinds of flags that it shouldn't.
