[meta-oe][PATCH] bpftool: start builds from a clean build dir

[mark.yang]

From: "mark.yang" <mark.yang@lge.com>

Nothing cleans ${B} between rebuilds and the kernel makefiles cache
their feature detection results there, so a sysroot-only change (say
binutils leaving DEPENDS) skips the relink and packages a stale
binary that still links libbfd.
