llvm-objdump fails on bunch of archs

hi,

as of the moment, llvm-objdump fails on every archs, except x86, arm, aarch64, mips and some other “minor” archs. some notable ones are PPC, Sparc, …

this is due to the lack of support for disasm component of those archs in MC. any plan, roadmap, or anybody is thinking about fixing this?

thanks.
