This change is not correct: selecting BR2_PACKAGE_JPEG and having
'jpeg' in KODI_DEPENDENCIES is the right thing to do. The 'jpeg'
package is a virtual package: it will itself depend on 'libjpeg' or
'jpeg-turbo' depending on the selected jpeg implementation.

Can you be more specific about which problems you have seen in relation
to jpeg support?

It's trying to use the C compiler to link with C++ libraries. Can you
share your Buildroot .config that exhibits the problem ?

Thanks,
