Subject: tools/llvm-bpf: move tarball packing to target/llvm-bpf
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=340c2ed2ef6578483f974e274bf6d638f953a246;p=openwrt%2Fstaging%2Faparcar.git

tools/llvm-bpf: move tarball packing to target/llvm-bpf

This ensures that the tarball is regenerated after make clean or after switching
to a different target
