BATU/BATL updates needed for macppc boot blocks

[Erik Bertelsen <erik%mediator.uni-c.dk@localhost>]

A few days ago, the powerpc based ports were updated with regards to
the handling of BAT's, but some updates still need to be done:

dependall ===> sys/arch/macppc/stand/bootxx
cc -O2 -Wall -msoft-float  -Werror   -D_STANDALONE -c 
/home/src/sys/arch/macppc/stand/bootxx/bootxx.c
/home/src/sys/arch/macppc/stand/bootxx/bootxx.c:260: macro `BATU' used with 
just one arg
/home/src/sys/arch/macppc/stand/bootxx/bootxx.c:260: macro `BATL' used with 
only 2 args
*** Error code 1
