--posix option for awk call to avoid problems with locale settings

[juergen-vogel]

I had the problem that awk saved 0.9*l[i] with a comma instead of a floating point. As a consequence the python script failed with the error message

ValueError: invalid literal for float(): 18,9

By adding the posix option to the awk call we get sure that the right floating point is used despite of your locale configuration.

Huh, what awk are you using that does this? This repo is outdated and obsolete, but this might be useful for z, which uses tons of awk itself.
