@jerboaa thanks for taking a look. I initially planned to document it in the makefiles somewhere but then found that we don't document why we use any flags there :( Plus there are a number of places where -D_GNU_SOURCE is used and I only want to document the reasoning for the VM which would then beg the question is to why the other uses are not documented somehow. So I just put it in os_posix.hpp where it was more likely to be seen when needed.
