Mark Hatle 10cdc3b27d populate_sdk_ext.bbclass: Make integrated buildtools optional
If the host system is expected to have enough capabilities that the
buildtools-tarball is not required, we don't need to bundle it.

This can save some significant space, especially when using with a minimal
eSDK.

minimal eSDK - core-image-minimal-qemux86-64

with buildtools-tarball     - 34 MB installer - 281 MB installed
without buildtoools-tarball - 11 MB installer -  48 MB installed

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.
