See README at

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...
