The change to the build flags solves the problem because hpcups and
pxljr rely on being able to override jinit_color_converter. I think the
fact that they're doing this points out a weakness in the libjpeg API -
there should be some better way to register a callback to change the
converter instead of hijacking the symbol from the library.
I think that for precise, turning off -Wl,-Bsymbolic-functions will be
the right way to fix this. It's possible, but unlikely, that it will
cause undesirable behavior regressions elsewhere... ultimately, it can
only be a regression if some other package is *trying* to do this symbol
interposition, has implemented it poorly, and users are being saved from
that bug by symbolic-functions.
