LibM: Fix linking with LibM when compiling Userland without -O2
While playing with conditionally disabling -O2 optimization when
building the Userland subdirectory, I discovered that we can no longer
link errors without -O2. This happens as LibM.so doesn't link to
anything else, resulting in no stack protector implementation. It
appears that optimization somehow avoids this problem?
To fix this inject LibC/ssp.cpp as we do with in dynamic loader.
