Thank you for the hint! It is very useful. I have already done it 
earlier today and I discovered that in my case the extensions fail to 
load due to:

libcapi-base-common.so.0: cannot open shared object file: No such file 
or directory

Now I am trying to fix the issue in the Yocto recipe for 
capi-base-common. I will provide feedback when I have any progress.
