Subject: toolchain-scripts.bbclass: customize prompt string for SDKs
X-Git-Tag: lucaceresoli/bug-15201-perf-libtraceevent-missing~8444

toolchain-scripts.bbclass: customize prompt string for SDKs

Introduce a new variable SDK_PS1 to customize prompt string for SDKs
when source script environment-setup-script. If variable SDK_PS1 is not
set or empty, nothing changed. Otherwise new PS1 with the value of
SDK_PS1 is used after source the sdk environment file.
