aic7-triple x build fixed in kbuild.git

akpm reported that:
make mrproper
make allmodconfig
make drivers/scsi/aic7xxx/

were broken in recent kbuild.git - and as a logical consequence removed kbuild.git from his -mm lineup.

I have now fixed it (stupid bug I made) and pushed out a fresh kbuild.git tree.

As previously announced I am not very active in kbuild land the next couple of weeks so I may be slow if there is any comments.

The fixed commit is included below.

aic7(3*x): fix firmware build

This patch adds the proper $(obj) and $(src) prefixes to dependency rules in aic7xxx makefile. Without this patch, there is a remote possibility that parallel make with a different output directory can fail.

Also changed the deprecated EXTRA_CFLAGS construct to ccflags-y syntax.

Fixed up patch to survive "make drivers/scsi/ -j" with BUILD_FIRMWARE enable. /Sam
