csky: Select ARCH_WANT_FRAME_POINTERS only if compiler supports it
Compiling csky:allmodconfig with an upstream C compiler results in the following error. csky-linux-gcc: error: unrecognized command-line option '-mbacktrace'; did you mean '-fbacktrace'? Select ARCH_WANT_FRAME_POINTERS only if gcc supports it to avoid the error. Signed-off-by: Guenter Roeck <linux@roeck-us.net> Signed-off-by: Guo Ren <guoren@kernel.org>
