building cross binutils fr30-unknown-none unsupported

I am trying to build a cross binutilsfor fr30. After running the configure command : 

./configure --target=fr30 --enable-cgen-maint --prefix=/<long_path>/myBinutils/new_build_fr30_cgen/

I run make command and got the next error :

** BFD does not support target fr30-unknown-none.
*** Look in bfd/config.bfd for supported targets.
make[1]: *** [configure-bfd] Error 1

how do I find the unknown-none ? any advice ?

The --target configure option is expecting a target triplet of the form cpu-vendor-os.

If you look at the big case statement in bfd/config.bfd that the error message is pointing you at, you'll see that for fr30 the supported target triplets match fr30-*-elf.

For example, configuring with ./configure --target=fr30-elf ... will get you to success or your next problem, as this abbreviation is canonicalised to a suitable triplet (by config.sub):

$ ./config.sub fr30-elf
fr30-unknown-elf

Hopefully with such a configuration, you'll end up with fr30-elf-ld, etc.
