The cross-compilation of VSS DLL from QEMU GA for Windows with MinGW fails because of disreparancy between compiler's and linker's stack protection options. The current qga/vss-win32/Makefile.objs filters out option '-fstack-protector-all' from compiler's option, but commit 63678e17c introduced changes in configure script, setting '-fstack-protector-strong' compiler option when available.
The '-fstack-protector-strong' option was not filtered out by the VSS DLL Makefile.objs file, resulting in linking error. Paolo Bonzini in the message http://lists.nongnu.org/archive/html/qemu-devel/2015-03/msg02719.html from 12.03.2015 suggested to fix the problem in a way similar to existing. The patch follows the advice and filters out both '-fstack-protector-strong' and '-fstack-protector-all' from compiler's options' list.
