Subject: blackfin: fix L1 data A overflow link issue
This patch fix below compile error:
"bfin-uclinux-ld: L1 data A overflow!"
It is due to the recent lib/gen_crc32table.c change:
46c5801eaf86e83cb3a4142ad35188db5011fff0
crc32: bolt on crc32c
it added 8KiB more data to __cacheline_aligned which cause blackfin L1 data
cache overflow.

If enabled, cacheline_aligned data is linked
