[PATCH] arch: drop duplicate exports of abort()

We now have exports in both architecture code in in common code,
which causes a link failure when symbol versioning is eanbled, on
four architectures:
kernel/exit.o: In function `__crc_abort':
exit.c:(*ABS*+0xc0e2ec8b): multiple definition of `__crc_abort'
This removes the four architecture specific exports and only
leaves the export next to the __weak symbol.
Fixes: mmotm ("kernel/exit.c: export abort() to modules")

Andrew, can you apply this to -mm on top of the other patch?
