The problem is that until yesterday, you could not build a powerpc64 
LINT, and so it was trying to build a PPC32 kernel with a 64-bit 
toolchain. An actual powerpc64 kernel does not include ofw_standard.c. 
This should be fixed now with r211483, so long as the LINT config is 
made with TARGET_ARCH set (and is not reused for 32 and 64-bit builds). 
There is a seat-belt mechanism I should add soon that will complain 
earlier about architecture mismatches like this. Thanks for your patience.
