Just to be clear, all the problems in the original mail, including
failure to detect COMPILER_TYPE automatically and building the wrong
type of binaries, were fallout from the original problem of not setting
MAKEOBJDIRPREFIX correctly.  It turns out if you use the build system
correctly, it works!  (Unfortunately, using it correctly requires
knowing about a whole lotta knobs to be set these days if your needs are
not vanilla.)
