Thanks for the tip about -Bsymbolic, that's what I want, but it doesn't seem
to do the job.
When I compile with -Bsymbolic -fpic I still get a GOT entry in 64 bit mode.
I just tried (linux amd64) on a trivial lib with 2 functions where the
second calls the first. And -Bsymbolic made the entry for the first
function disappear from the .rela.plt section. So it makes some difference
at least.
