Just fine?

But as my own compile tests showed, neither sata_vsc.c or libata-core.c 
/ libata-scsi.c were ever compiled into sata_vsc.o and libata.o (for use 
at kernel link time) during a 'make bzImage modules'.

Makes sense. But it doesn't seem to work that way in practice.

Run a kbuild using that .config and you'll probably see the problem too..
