[Buildroot] [PATCH 01/20] support/tests: allow properly indented config fragment

[Yann E. MORIN <yann.morin.1998@free.fr>]

All,

This is version 2 of the patch. Version 1 has been just reviewed now by
Arnout, after which I sent v3:
    https://patchwork.ozlabs.org/patch/790525/

So, please disregard this one; use v3 instead (but still before the rest
of this series).

Thanks!

Regards,
Yann E. MORIN.

> Currently, defining a config fragment in the runtime test infra requires
> that the fragment not to be indented. This is beark, and causes grievance
> when looking at the code (e.g. to fix it).
> 
> Just strip out all leading spaces/tabs when writing the configuration
> lines into the config file, allowing in-line indented config fragments,
> like so:
> 
>     class TestFoo(bla):
>         config = bla.config + \
>             """
>             FOO=y
>             # BAR is not set
>             """
