[Buildroot] [PATCH 2/2] support/dependencies/dependencies.sh: check for Python argparse module

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

Thomas, All,

On 2018-03-03 15:36 +0100, Thomas Petazzoni spake thusly:
> The script support/scripts/check-uniq-files uses the argparse Python
> module. In most recent Python versions (starting with 2.7), the
> argparse module is part of the standard library, and we already check
> for the availability of Python in
> support/dependencies/dependencies.sh.
> 
> However, when running on an ancient distribution with Python 2.6, the
> argparse module is not part of the Python standard library, but
> available as an external module. Without this module, the build fails,
> because check-uniq-files, which is used in target-finalize, fails to
> run.
> 
> To avoid this failure, this commit adds a check in
> support/dependencies/dependencies.sh to verify that the argparse
> module is available.
> 
> Signed-off-by: Thomas Petazzoni <thomas.petazzoni@bootlin.com>
