Henry was correct about the paths.  I managed to complete the build with:

make all OPT="-dNO_THREADING -Fl/usr/lib/arm-linux-gnueabihf -Fl/usr/lib/gcc/arm-linux-gnueabihf/4.6"

I'm not sure I need the -dNO_THREADING, but I left it in from Joost's suggestion.

The new build was then installed with:

sudo make install PREFIX=/usr
sudo make install sourceinstall PREFIX=/usr  [Not sure if I need this as well?]

Recreated the symlink with:

sudo rm -f /usr/bin/ppcarm
sudo ln -s /usr/lib/fpc/2.7.1/ppcarm /usr/bin/ppcarm

Then created the new config with:

sudo /usr/lib/fpc/2.7.1/samplecfg /usr/lib/fpc/2.7.1 /etc

This seems to do the trick, I could compile my Pi projects again, although I had to add the two paths
to my build commands.

What are the files crti.o, crtn.o, crtbegin.o, crtend.o used for by Free Pascal?
Is this dependency something new, or has it always been there?

Thanks for all of your suggestions,

Kind regards,
