Neither binutils nor gcc support for C-SKY are in the upstream 
repositories yet.  We should be resubmitting the binutils port soon 
(with bug fixes to address the test failures that caused it to be 
rejected the last time), and the gcc port will follow that shortly.

The target triplets we have been testing are csky-elf, csky-linux-gnu, 
and csky-linux-uclibc.  Note that the gcc port will only support v2 
processors/ABI so that is the default ABI for these triplets.

I'm not familiar with the Fedora tools, but to build a complete 
toolchain you'll need library support as well and I'm not sure what the 
submission status/plans for that are.  E.g. Mentor did a newlib/libgloss 
port for local testing of the ELF toolchain and provided it to C-SKY, 
but pushing that to the upstream repository ourselves is not on our todo 
list.
