Containerless tools

[no92]

This allows for building tools that don't compile and link against the container but against the host machine. This is useful for building a QEMU in bootstrap for instance:

tools:
  - name: host-qemu
    containerless: true
    from_source: qemu
    configure:
      - args:
        - '@THIS_SOURCE_DIR@/configure'
        - '--prefix=@PREFIX@'
    compile:
      - args: ['ninja']
    install:
      - args: ['ninja', 'install']

This allows the result QEMU to use host libraries, resulting in more features of it being available and not having to ship dozens of host tools.

I think the following code can be simplified, since python3 already has builtin function any for ORing all the elements in the iterable.

And this as well. Didn't see these occurences the first time.

Applied the suggested code changes.

Can we get this merged? Having a dmalog Qemu in bootstrap would be really nice, and as far as I can tell, all concerns here have been addressed.
