 I think the problem is actually in usr.bin/xlint/Makefile.inc, which
 now uses the MACHINE* variables in the following manner:
 
 # On the m68000, MACHINE_CPU is "m68k", but we have different
 # target parameters (namely, long double is a different size
 # on the m68000), so we special case the directory name here.
 .if ${MACHINE_ARCH} == "m68000"
 ARCHSUBDIR=     m68000
 .elif ${MACHINE_ARCH} == "mips64eb" || ${MACHINE_ARCH} == "mips64el"
 ARCHSUBDIR=     mips64
 .else
 ARCHSUBDIR=     ${MACHINE_CPU}
 .endif
 
 With MACHINE_ARCH=powerpc64/MACHINE_CPU=powerpc that ends up
 with ARCHSUBDIR=powerpc, with builds a 32-bit lint.  I would
 like to change this to something like
 
 .if ${MACHINE_ARCH} == "mips64eb" || ${MACHINE_ARCH} == "mips64el"
 ARCHSUBDIR=     mips64
 .elif exists(${.CURDIR}/../arch/${MACHINE_ARCH})
 ARCHSUBDIR=     ${MACHINE_ARCH}
 .else
 ARCHSUBDIR=     ${MACHINE_CPU}
 .endif
 
 which fixes my problem and removes the m68000 special case as a
 side effect.  I'm so far out of my depth with the mechanics of
 the build system, however, that I don't know if this change
 would be fixing something that is broken, or if the thing that
 is broken is setting MACHINE_CPU=powerpc.  Note that lint isn't
 the only new problem I've got; I'm also getting unresolved symbols
 from the libgcc4 libraries when loading c++ programs (i.e. groff)
 so I think I must have hit a similar problem in there somewhere too.
 
 Errors in kernel and powerpc code I can deal with, but the build
 system is way scarier.
