No, this is wrong. On amd64, you should *not* use -fPIC in make.conf. 
That's been policy since 2004.0. It is required that -fPIC is used for 
shared things (such as shared libraries) and it is required that -fPIC 
is not used for non-shared things (such as binaries). Thus, it must not 
be set in make.conf, otherwise you break this. If something does not 
compile without using -fPIC in CFLAGS, then that is a bug.

Hardened is different, however.
