Create ostrip to strip object files

[ghost]

strip is part of GNU binutils. LLVM also provides llvm-strip.

ok so there isn't one right now but I don't see this as a big deal either... but im getting lots of stuff piled up 😄

I suggest to change the title to something like "implement new ostrip binary" or similar, with some outline which options it will likely have. the option list of strip is quite extensive, I'm not sure what ostrip may support (only "drop debugging symbols"?).

so we will likely be able to strip debug symbols, public names, entire sections, and relocations. I will try to keep the same options as strip when we do this.
