I used an no upstream toolchain to verify coredump backtrace, which use
the EM_CSKY_OLD equals to 39. We have changed the EM number to 252 in
our newly released toolchain with compatibility to EM_CSKY_OLD.
See binutils/include/elf/common.h:
/* C-SKY historically used 39, the same value as MCORE, from which the
   architecture was derived.  */
#define EM_CSKY_OLD             EM_MCORE
