Maybe it's _start vs __start ENTRY problem in ld(1) which I posted.
You have to fix ld in binutils or add -e __start in bsd.prog.mk.

FYI, what I tried is:

(1) Build usual toolchain for sh3el:
% cd /usr/src
% sh build.sh -m dreamcast -D [somewhere for ${DESTDIR}] tools

(gnu/dist/toolchain/ld/emulparams/shelf_nbsd.sh should be fixed first)

(2) Build gcc-3.3:
% tar jxvf gcc-3.3.tar.bz2
% cd gcc-3.3
% ./configure --target=shle--netbsdelf \
--with-as=/usr/tools/sh3el/bin/shle--netbsdelf-as \
--with-ld=/usr/tools/sh3el/bin/shle--netbsdelf-ld \
--disable-shared --enable-languages=c,c++
% gmake
[I might see some errors but not sure..]
% su
# gmake install

(3) Build binaries with make script
% cd /usr/src
% ${TOOLDIR}/bin/make-dreamcast CC=/usr/local/bin/shle--netbsdelf-gcc \
HAVE_GCC3=yes MKPROFILE=no TOOLCHAIN_MISSING=yes BUILD_tools=no -k build

(I'm not sure 'make -k build' works. Maybe you should visit
 directories (lib/csu, lib/libc, libexec/ld.elf_so..) manually)

Marcus has already put some binaries, but I'll put other binaries later.
