On an RPI2 model B, invoking 
make -j4 -DNO_CLEAN MACHINE_ARCH=armv7 buildworld > buildworld.log
(after a cleandir)
the log promptly reports
make[1]: "/usr/src/Makefile.inc1" line 162: SYSTEM_COMPILER: Determined that CC=cc matches the source tree.  Not bootstrapping a cross-compiler.
make[1]: "/usr/src/Makefile.inc1" line 450: To cross-build, set TARGET_ARCH.
*** [buildworld] Error code 1

make: stopped in /usr/src

The kernel is r322520, sources are at 324424. Kernel r324342 does likewise.

Thanks for reading, and any suggestions.
