[PATCH bpf-next 1/2] libbpf: Add missing per-arch include path

[Björn Töpel]

From: Björn Töpel <bjorn at rivosinc.com>

libbpf does not include the per-arch tools include path, e.g.
tools/arch/riscv/include. Some architectures depend those files to
build properly.

Include tools/arch/$(SUBARCH)/include in the libbpf build.

Fixes: 6d74d178fe6e ("tools: Add riscv barrier implementation")
