From building the selftest in general, I'm getting:

clang -O2 -target bpf -c bpf/nat6to4.c -I../../bpf -I../../../../lib -I../../../../../usr/include/ -o /root/daniel/bpf/tools/testing/selftests/net/bpf/nat6to4.o
In file included from bpf/nat6to4.c:27:
In file included from /usr/include/linux/bpf.h:11:
/usr/include/linux/types.h:5:10: fatal error: 'asm/types.h' file not found
#include <asm/types.h>
^~~~~~~~~~~~~
1 error generated.

Could we reuse the build infra from tools/testing/selftests/bpf/ for nat6to4.c?
