app-emulation/qemu: filter out -fcommon

Next qemu release should have a proper fix for symbol collision:
  $ git grep -P '[^a-z_]machine_init_done[^a-z_]' | cat
  softmmu/vl.c:bool machine_init_done;
  stubs/machine-init-done.c:bool machine_init_done = true;

I'm not comfortable backporting the change and only
filtering out -fcommon as a workaround. We'll remove
a workaround in next release.
