I just build a kernel, using build.sh.  As I usually do, I did a 'cd' to
the build directory and did a 'make install'.  It failed with these
messages:

make: "/usr/src/sys/conf/Makefile.kern.inc" line 79: Malformed conditional

make: stopped in /usr/BUILD/obj/sys/arch/i386/compile/GG1

Using nbmake from the tools directory didn't help; the build itself (of
all of kernel and userland) was done with a clean obj and tools directory.
