When building qga-bss.dll with 64-bit mingw toolchain v. 4.9.2, the
qga-vss.dll linking fails with unresolved symbols from libssp,
stack protection support, like the following message:
.../qga/vss-win32/install.cpp:52: undefined reference to `__stack_chk_fail'
The patch fixes the problem by adding libssp to the qga-vss.dll
libraries list.
