Disable DLL loading if without system linker
Some platforms (musl, aarch64) do not have a working dynamic linker
implemented in the libc, even though we might see dlopen. It will
ultimately just return that this is not supported. Hence we'll add
a flag to the compiler to flat our disable loading dlls. This is
needed as we will otherwise try to load the shared library even
if this will subsequently fail. At that point we have given up
looking for static options though.
