unable to build RELENG_6

after checking out RELENG_6 today to do some unrelated testing, i find 
that i can no longer build the kernel.  the config is a copy of GENERIC.

"make depend" ends with this:

cc -O2 -fno-strict-aliasing -pipe  -nostdinc -I/usr/include -I. 
-I../../../dev/aic7xxx/aicasm   -o aicasm aicasm.o aicasm_symbol.o 
aicasm_gram.o aicasm_macro_gram.o aicasm_scan.o aicasm_macro_scan.o -ll
./aicasm -nostdinc -I-  -I. -I../../.. -I../../../contrib/altq

../../../dev/aic7xxx/aic7xxx.seq
