[patch 3/6] always build arch/ia64/lib/xor.o

[akpm]

From: Lee Schermerhorn <Lee.Schermerhorn@hp.com>

Always build ia64 xor.o because multiple config options now depend on it.

Necessary to build .20-mm* on ia64 when, e.g., CONFIG_ASYNC_TX_DMA is
defined.  Don't know if '_ASYNC_TX_DMA makes sense on ia64.  If not, maybe
Kconfig should preclude it.

Could have defined a Kconfig option that defaults to true if MD_RAID456 ||
ASYNC_TX_DMA to control building of xor.o, but xor.o is only 848 bytes and
this IS ia64...
