SMM: link against libgcc
The non-relocatable SMM code was changed to link against libgcc a while back
so that printk could use built-in division instead of a hand crafted div()
function. However, the relocatable SMM code was not adapted by mistake.
This patch links the relocatable SMM against libgcc, too, so we can enable it
for Haswell.
