In the failure case, the above command invokes the make command
inside ${.OBJDIR}, which contains no Makefile.  ${.CURDIR} should
always point to the current directory in the source tree.
I think this should work:

diff --git a/sys/dev/disk/aic7xxx/ahc/ahc_pci/Makefile b/sys/dev/disk/aic7xxx/ahc/ahc_pci/Makefile
index 1973ce1..7b1f3f2 100644

Using fresh master (January 17th 2012)
make -j 3 buildkernel
fails on UP system.

(quickkernel succeds here)

Make -j 10 buildkernel
succeeds on 8 core system.

-
===> dev/disk/aic7xxx/ahc/ahc_pci
( cd ... ; make aic7xxx_reg.h )
make: don't know how to make aic7xxx_reg.h. Stop
