the message is given when linking, while -fPIC needs to go into the compile
step. Building objects without -fPIC to be used in a shared library results in
a linker message about unresolvable relocations without saying that -fPIC might
be involved.

this is not amd64 specific (only works on i386).

Maybe you could forward this upstream? See the gcc-snapshot package for the
manual sources.
