I can use the command bitbake fsl-image-qt5 -c populate_sdk to compile the sdk toolchain, and I've installed and verified the sdk is working successfully. However I came across to a project which require g++ compiler version 4.8, and I checked that the gcc and g++ toolchain in yocto is 5.3. How do I configure my bitbake to build a sdk of gcc/g++ toolchain of older version 4.8?
