binutils-gold 2.20-4ubuntu4 (amd64 binary) in ubuntu lucid

 Gold is a new linker, still in development, which is faster than the
 current linker included in binutils. It currently fails to link some
 applications and libraries (i.e. won't link usable kernels).
 .
 This package diverts the GNU linker (ld) with the experimental gold
 linker.
