During the internal review we arrived to this setup, to keep the
libraries separate from the basefw binary.
One of the reason is that SOF project is not likely not going to release
external libraries, they are mostly vendor/product locked.
To make the life easier for the vendors (and distributions, packagers)
we concluded that it is better to keep them separate.

The option is there to specify custom path as well in case it is needed.

My initial approach was this as well, but after a long debate it got
revised.
