This seems to be caused by recent
2c717948d91540016067f87bb3e0913067d42647 although it shouldn't have:
argparse is part of python2.7 (not sure about minor version though) and
our poky toolchain 1.5.4 uses Python 2.7.3
Could it be that python is somehow misconfigured in the toolchain? Shall
we add argparse to sysroots/i686-pokysdk-linux/usr/lib/python2.7
manually or try to update toolchain to newer version?
Max.
