Missing arch/ and configs/ subdirectories when "git checkout" 7.11 to 7.15

I'm trying to get Atmega128 work with NuttX and when I did "git checkout 7.15" noticed that arch/ and configs/ directories were empty.

I think it was caused because in the past some directories were separated from nuttx/ kernel.

This issue happens from 7.11 to 7.15! So version <= 7.10 seems fine as well version >= 7.16.

@patacongo I remember you said you have all NuttX tarball versions saved in your computer.
Could you please update it to some free online file sharing? (i.e. https://www.pcloud.com offer 10GB for free)
