Summary: The `-dynamic` flag does two things: * In the code generator, it generates code designed to link against external shared libraries. References outside of the current module go through platform-specific indirection tables (e.g. the GOT on ELF). * It enables a "way", which changes which hi files we look for (`Foo.dyn_hi`) and which libraries we link against. Some specialised applications want the first of these without the second. (I could go into detail here but it's probably not all that important). This diff splits out the code-generation effects of `-dynamic` from the "way" parts of its behaviour, via a new flag `-fexternal-dynamic-refs`.
