[LEDE-DEV] Strange build error

[Zoltan Gyarmati]

Dear All,

i'm fighting with an odd build error on my build server VPS, using
current master and the RT5350F-OLINUXINO profile:

When trying to re-build the LEDE tree (after a successful initial
build), i get this error:

The odd thing is that the same config on my laptop (Debian
testing/Buster) builds and rebuilds correctly, while on the VPS (Debian
9/Stretch) it fails with the error above.
I've checked all the dependencies, digged into the environment to figure
out what is the significant difference, but i couldn't hunt this down.
My best guess it that is related to the fact that the build server runs
on a VPS, but no solid evidence on this yet...

Do you have maybe an idea where to look?
