OK.
toolchain - rx-unknown-linux
binutils-2.32 include rx-unknown-linux support.
$ configure --target=rx-unknown-linux
$ make

gcc - please use my git repo.
git://git.pf.osdn.net/gitroot/y/ys/ysato/gcc.git rx-trunk
$ configure --target=rx-unknown-linux --enable-languages=c --disable-shared \
--disable-threads --with-uclibc --disable-libssp --disable-libquadmath \
--disable-libgomp --disable-libatomic
$ make

This toolchain can build u-boot / linux.

target program.
u-boot
git://git.pf.osdn.net/gitroot/y/ys/ysato/uboot.git rx
pre build binary in bellow.

linux
git://git.osdn.net/gitroot/uclinux-h8/linux.git rx
https://osdn.net/users/ysato/pf/qemu/dl/zImage

Since linux is still incomplete, it may be problematic.
