I am trying to build with the most recent of gcc that I found that still use gcc-core:

To have any chance to build gpc you need a patch to gcc. Using gcc-core is irrelevant: it just saves download time compared to full gcc. It matters is gpc was adapted (ported) to given gcc backend.
Concerning your first message: most gpc build problem are in fact gcc build problems. Namely, building older gcc versions (needed by gpc) is getting tricky on modern systems. So as first step you may try just building old gcc (say 3.4.6 or 4.1.1). gpc contains patches for some build problems, but new ones appear...
