[Qemu-trivial] [PATCH] When building qga-vss.dll with 64-bit MinGW toolchain, qga-vss.dll linking fails with unresolved symbols from libssp, stack protection support, like the following message:

[Joseph Hindin]

.../qga/vss-win32/install.cpp:52: undefined reference to `__stack_chk_fail'

The patch fixes the problem by adding -fstack-protector-all option to the
linker options' list.
