When building the latest samples/bpf on LoongArch Fedora
make M=samples/bpf
There are compilation errors as follows:
In file included from ./linux/samples/bpf/sockex2_kern.c:2:
In file included from ./include/uapi/linux/in.h:25:
In file included from ./include/linux/socket.h:8:

./arch/loongarch/include/asm/loongarch.h:13:10: fatal error: 'larchintrin.h' file not found

1 error generated.
larchintrin.h is included in /usr/lib64/clang/14.0.6/include,
and the header file location is specified at compile time.

There's still one location in XDP_SAMPLE_CFLAGS, do we need the $(CLANG_SYS_INCLUDES)
there as well?
