The big problem is make.conf isn't included soon enough to get the
BINFORMAT=elf, instead it relies on test mostly of
.if ${MACHINE} == "alpha"
BINFORMAT?= elf
.else
BINFORMAT?= aout
.endif
This is also why when building elf libraries that they are installed by
default into /usr/lib/aout. Can you say bad magic number?
This needs to be fixed to get an elf machine with a buildworld/makeworld.
One work around maybe to go into your src/share/mk directory and at the top
of each makefile put a BINFORMAT=elf just to be shure.
