The content of the ABI manual is quite old, binutils souce code seems
much reliable to refer to. binutils/bfd/elf32-csky.c says,
only three relocations are abiv1 exclusive:
R_CKCORE_PCREL_JSR_IMM11BY2
R_CKCORE_PCREL_IMM8

I've generated binaries/core with an upstream toolchain, however the
divzero testcase doesn't cause any coredump, so I used a zeroptr
testcase instead.

Ok, I'll add check for C-SKY here.
