* perf is failing to build for me since this oe-core commit:

perf: make a copy of kernel source to perf workdir
the problem is that perf sources in kernel older than 4.8 (in my case
4.4) are depending on the "global" include headers outside tools
directory, e.g. swab.h in:
kernel-source/tools$ git grep swab.h
perf/MANIFEST:include/linux/swab.h
perf/MANIFEST:include/uapi/linux/swab.h
perf/util/include/asm/byteorder.h:#include "../../../../include/uapi/linux/swab.h"
this was resolved in 4.8 with:

perf tools: Remove tools/perf/util/include/asm/byteorder.h
Not used anymore. This also stops include linux/swab.h directly
from the kernel sources, remove that reference from the MANIFEST.
and few more changes to make tools/include more complete and standalone:
tools/include in 4.15:
asm asm-generic linux tools trace uapi
tools/include in 4.4:
asm asm-generic linux tools
but copying the include header even for kernels which don't really
need it doesn't add big overhead, so just copy include to perf sources
for all kernels.
