Like SublimeText, I think atom should have a simple build system for C/C++, Java, Python… the inner build system can make it easy for some simple task rather than run programs in command line.
Should support a build system for some common language?

I suspect that the Atom team intends the core editor to remain strictly language-agnostic; language-specific tools will appear as packages.
It should be exceptionally easy, though, to write packages for most command line build systems. Look at Make Runner, a package for running make files: the whole codebase is ~60 lines long.
