When building perf for 5.4+, we have some new files that need to
be copied (and synchronized) due to structural changes in the
kernel source tree.
Some of the issues these fixes are warnings, but none the less,
they are worth fixing.
- We copy arch/${ARCH}/Makefile, since it is source by some perf
Makefiles
- We copy scripts/, since the perf utilities are looking for files
in that directory stucture.
- We have *three* copies of ctypes.h in the tools/* hierarchy
during the build. If the tools/perf/util/include/linux/ variant
is used, it will trigger build errors since it is not complete.
We copy the kernel's main include/linux/ctype.h to ensure they
are in sync.

QEMU Emulation Targets ====================== To simplify development, the build system supports building images to work with the QEMU emulator in system emulation mode. Several architectures are currently supported in 32 and 64 bit variants: * ARM (qemuarm + qemuarm64) * x86 (qemux86 + qemux86-64) * PowerPC (qemuppc only) * MIPS (qemumips + qemumips64) Use of the QEMU images is covered in the Yocto Project Reference Manual. The appropriate MACHINE variable value corresponding to the target is given in brackets.
