OK.
I made h8300-*-linux target patch for release version.
Please apply and rebuild to "h8300-unknown-linux"
http://sourceforge.jp/projects/uclinux-h8/releases/p14625

My toolchain configure options bellow
* binutils
../configure --prefix=/home/ysato/h8-linux --target=h8300-unknown-linux

* gcc
../configure --target=h8300-unknown-linux --prefix=/home/ysato/h8-linux \
--disable-ssp --disable-libssp --disable-mpc --disable-gmp --disable-mpfr \
--disable-threads --disable-shared --disable-libmudflap --disable-libgomp \
--disable-zlib --disable-libquadmath --without-libc --disable-libatomic \
--enable-languages=c

Thanks.
