 -Wl,-shared means "pass -shared to the linker and do nothing else"
 while -shared means "tell the compiler driver to build a shared
 library", which includes both passing -shared to the linker and also
 doing other things. Without the other things, you'll among other
 things get the wrong crstuff and it won't work.
