ld: binutils-2.19.51.0.14-37.fc12
gold: CVS snapshot from date: 20100309
Originaly I scheduled: "prelink openssl openssh ecryptfs-utils xcb-util gtk2
kdebase-workspace python perl ruby vlc glib2 glibc rhythmbox totem qt gcc
kernel firefox xulrunner thunderbird ImageMagick binutils" but some of them
failed to build so it's pointless to show 'how long they have run'. Plus I
forgot on qt in 'ld-run' but we know it runs ~2h already.

Apart from xulrunner and thunderbird where gold looses dozens percent, results
are comparable.
