[cfe-dev] How can I make clang/llvm use specific toolchain?

- This means that you used cross-binutil to link ELFs. But (the
library and?) header files are of SB2?
- Did you execute clang under SB2 environment(context)? and used
cross-binutil out of SB2?

Thank you for your sharing of your knowledge.
The usage of the options above would be helpful.

Thank you very much!
