Platform i386

With "setenv DESTDIR /usr/src/ELF;cd /usr/src;make build" I get:

cc -x assembler-with-cpp -traditional-cpp -D_LOCORE -I../../../../../../lib/libkern/arch/i386 -I../../. -I../../../../../../arch -I../../../../../.. -nostdinc -I../../../../../../../gnu/sys -DLKM -DDIAGNOSTIC -DDEBUG -DEXEC_ELF -DMAXUSERS=16 -D_KERNEL -Di386  -nostdinc -idirafter /usr/src/ELF/usr/include -c -traditional-cpp ../../../../../../lib/libkern/arch/i386/strrchr.S

Stop.

What did I do wrong?
