Here's a new patch which only implements the syscall stubs needed by
wine (amd64_set_gsbase and i386_set_fsbase).
This patch also corrects a critical mistake: in setters, the pointers
are passed by reference just like with getters (this confusion led me
to report non-bug #637528, more details there).
