Merge remote-tracking branch 'remotes/bonzini/tags/for-upstream' into staging

Another round of small fixes.  I am not including the
virtio-blk fix, because Wen only posted a prototype and the changes
I made were pretty large.  It definitely needs another pair of eyes
(but it is a 2.3 regression and a blocker).

* remotes/bonzini/tags/for-upstream:
  Use $(MAKE) for recursive make
  kvm-all: Sync dirty-bitmap from kvm before kvm destroy the corresponding dirty_bitmap
  util/qemu-config: fix regression of qmp_query_command_line_options
  target-i386: clear bsp bit when designating bsp
  qga: fitering out -fstack-protector-strong
  target-i386: save 64-bit CR3 in 64-bit SMM state save area
