"overlay" and "local-patches" folders missing while installing

[artynet]

the comand make install doesn't take care of installing this two fundamental missing pieces. I had to copy them into my custom installation path which is :

$HOME/Programs/ct-ng/lib/crosstool-ng-1.22.0-42-g1fbfd12

otherwise the build breaks with this error :

[ERROR]  
[ERROR]  >>
[ERROR]  >>  Build failed in step 'Installing C library'
[ERROR]  >>        called in step '(top-level)'
[ERROR]  >>

[ERROR]

please take care of it....
