What about adding a new package fpc-cross that adds support for cross compiling
with fpc by pulling all these linkers or maybe add a set of fpc-cross-${arch}.
This way if I want to enable cross compiling for armel on amd64 then I would
install fpc-cross-armel

I think there is a better solution. For now we have this at the end of
/etc/fpc.cfg:
This means that every file there will be included.
If we place the regular config file there and we surround it by #ifdef ${arch}
then we can fix this without having all arch configs in the same file

If this is not clear I explain: we replace fpc.cfg to become a regular file that
contains only #CFGDIR directive. Each package will install its config file while
paying attention to surround all its config with the correct #ifdef. This allows
the config to be extended automatically when one installs a foreign compiler.

Yes, sorry for this lapsus

Thanks for the hard work you are doing.
