The elf crt object is built from src/lib/csu/i386-elf. You'll need
to build and install that.
Before you can "cc -elf foo.c", you need libc and libgcc in elf format.
The elf tools you build from src/gnu/usr.bin/binutils only work with
objects that they build, so you can't use the installed aout libraries.
I'd suggest that you only build an elf libc.a and libgcc.a, not shared
versions or you might hose yourself. So cc -static is your friend. 8-)
And if you aren't game to install elf libraries in /usr/lib, then
use -nostdlib and -nostartfiles and give gcc explicit paths to the
build directories of crt1.o, libc.a and libgcc.a.
