CMake: use correct link flag for MinGW(GCC) static-runtime build

Browse Source 
When using MinGW compiler and Qt is configured with "-static-runtime",
we should pass "-static" to g++ while linking, like Qt 5, instead of
"-Wl,-Bstatic", to get rid of dependencies on libgcc_s_seh-1.dll,
libwinpthread-1.dll and libstdc++-6.dll.

Because syncqt doesn't link to any Qt library,
"target_link_options(${target} INTERFACE -static)" has no effect on it.
So we should use "PRIVATE" instead of "INTERFACE" for executables.

Pick-to: 6.6 6.5
