Ah, okay.

But Thomas, I can't use BR2_PACKAGE_JPEG for turbovnc because it uses
specific ABI (the so called TurboJPEG ABI)
from libjpeg-turbo package and vanilla jpeg does not provide it.

https://libjpeg-turbo.org/About/TurboJPEG

At least, *if* I remember correctly, turbovnc nagged something about
missing function when I tried to compile against vanilla jpeg.
