It seems the break was caused by this part of the change:

DPADD= ${LDR_INTERP} ${LIBOFW} ${LIBFDT} ${LIBSA}
LDADD= ${LDR_INTERP} ${LIBOFW} ${LIBFDT} ${LIBSA}
The integrated assembler of clang doesn't support the -mppc64bridge option,
that is why it was removed.
Fortunately, Justin noticed that kboot is only made for powerpc64 systems
and fixed this in r348028.
