The Target writers do a static cast and return their layout's which i feel is not a nice design, IMO. I think you could safely derive from OutputELFWriter and create MipsOutputELFWriter. This would save the same amount of duplicated code too. Thoughts ?

I can inherit MipsOutputELFWriter from OutputELFWriter, but finally I
need MipsExecutableWriter and MipsDynamicLibraryWriter. If I inherit
both these classes from MipsExecutableWriter I will have to duplicate
the code from the ExecutableWriter and DynamicLibraryWriter.
