Thanks for the report. 

I just reproduced the issue locally, with similar log:

  CC      drivers/target/target_core_sbc.o
{standard input}: Assembler messages:
{standard input}:2644: Error: pcrel offset for branch to .LS0015 too far (0x3e)
{standard input}:2653: Error: pcrel offset for branch to .LS0015 too far (0x34)
{standard input}:2659: Error: pcrel offset for branch to .LS0015 too far (0x2c)
make[2]: *** [scripts/Makefile.build:272: drivers/target/target_core_sbc.o] Error 1
m

And when I changed the function align option from 64 to 32, the
compilation did pass, so this looks to be related with the alignment
option.

I'm very familiar with compiler, and will try to check more.

I know it works on x86_64, but don't know how about other
architectures, and if 'csky' is the only not working one, one
workaround I can think of is to add kconfig dependency for !csky 

Thanks,
Feng

Sorry, typo, should be "not very familiar" :P
