Disable sibcalls from syscall_linkage functions.

This fixes the bug for me.  I will do the usual testing, and then check it in. 
Since this is a kernel miscompilation problem, I will add the patch to mainline
and gcc-3.4, and also try to get it into gcc-3.3.  The testing will take a few
days.  I will try building a kernel to see what happens, but I won't try
booting it.
