It might be because it doesn't work. The following box works with the
"old" style, but fails with the "new" style:
[root@xeon:/usr/src] # make buildkernel KERNEL=XEON
[massive sniop]
/tmp/ccM70700.s:2514: Error: Subtraction of two symbols in different
sections "IdlePTD" {.data section} - "KERNBASE" {*UND* section} at
file address 1884.
/tmp/ccM70700.s:2517: Error: Subtraction of two symbols in different
sections "IdlePTD" {.data section} - "KERNBASE" {*UND* section} at
file address 1903.
