You can't start doing this in a tree where you have already built
Python using the default way -- you have to use a pristine tree. The
reason is the funny way Make's VPATH feature works, it sees the .o
files in the source directory and then thinks it doesn't have to creat
the .o file in the build directory. I think a "make clobber" at the
top level would probably eradicate everything that confuses Make.
