But I'm not sure who should pick this up.

xsysace should just depend on either PPC or OF.  It is applicable to
more than just virtex/spartan systems (I know of at least one
non-virtex 440 board with a systemace, hence the 4xx usage), and it is
conceivable that it would be used on other architectures.

XILINX_VIRTEX makes some sense for hwicap

PPC_OF doesn't have any real meaning anymore.  PPC would be better.
