LO should work with bot libjpeg and libjpeg-turbo.  And given that 
there's zero checking for specific details in LO's configure.ac for the 
--with-system-jpeg case, I'd assume that various jpeg-9* would all work. 
  But you'd need to check; configure checks are typically only added 
once somebody ran into a non-working combination.

And note that your issue is with LO's bundled external/pdfium, not core 
LO code, building against system jpeg.  Arguably, whatever missing 
configure checks are missing from pdfium's configure; so if you come up 
with a fix for that, that should probably go to the pdfium upstream.
