The kernel module build process uses bsd.own.mk from /usr/share/mk, which should define MK_CLANG_IS_CC. If it doesn't, but your kernel source references it, there is a mismatch. In some cases, you could fix it by setting MAKESYSPATH to the share/mk dir under your source tree. There is still no guarantee your module will build or load correctly. As Doug Barton said in reply to r232473: "Building ports where the sources and the installed kernel differ is not a supported configuration. The fact that it happens to work most of the time is a bonus." That said, i think it may be time to bow to the pressure, and just put a fixup for this issue in kmod.mk, and the other .mk files, like I initially did in r232473, but with a BIG FAT WARNING printed, so you at least know you are attempting to shoot your extremities. :)
