Bug 14471

Prebuilt eSDK toolchains from download.yoctoproject.org take long time (~30 minutes) to install, as the install process tries to contact Hash Equivalence Server typhoon.yocto.io:8686 of the original builder multiple times and eventually times out.

$ ./poky-glibc-x86_64-core-image-minimal-aarch64-qemuarm64-toolchain-ext-3.1.8.sh

SDK has been successfully set up and is ready to be used.
Each time you wish to use the SDK in a new shell session, you need to source the environment setup script e.g.
 $ . /OE/poky-sdk-3.1.8/environment-setup-aarch64-poky-linux
