Add objcopy() rule to compiler modules

[NiklasRosenstein]

A rule objcopy() to invoke the GNU objcopy tool should be added.

I'm thinking about delaying this when there would be a higher demand and the need to provide an abstract interface to the objcopy tool. For now, it can easily be written with a standard target() definition.

testbin = target(
  inputs = testelf,
  outputs = [join(project_dir, 'test.bin')],
  command = ['objcopy', '-O', 'binary', '%%in'],
)

With Craftr 0.20.0-dev, this target would look like this instead:

testbin = Target(
  command = 'objcopy -O binary $in',
  inputs = teself,
  outputs = [path.local('test.bin')],
)

I'd sure like to be able to create an ObjCopy translator with the command specified and then use the ObjCopy translator with various inputs and outputs.

Ok, I've added an Objcopy class to the unix extension module, see 91c6d7b. You would use it like this:

from craftr.ext import unix
objcopy = unix.Objcopy(program='arm-eabi-objcopy')
testbin = objcopy.objcopy(
  inputs = testelf,
  output_format = 'binary',
)

Note that this is very experimental as I don't really have something to test this here. By default, the class will call objcopy --help and use regex to find the supported targets. If you choose an output_format or input_format that was not in that list of supported targets, there'll be an error.

You can fork my project, but I'll give it ago sometime soon.

I'd have a to build a cross-compiler first, no? :)

[NiklasRosenstein]

Ah I mess up the two issues. :) See https://github.com/craftr-build/craftr/issues/3#issuecomment-163739727

I've created a project to make it "easy", you're welcome to give it a try.
