The Berkeley DB library is not used by the kernel. As you said yourself,
it is used by the firmware assembler, which is a userland application
like any other. The Berkeley DB library is a quite small library for easy
access to a very simple filebesed database. It cannot be compared with
MySQL or any other SQL database. It's more like the map<> or vector<>
templates found in STL.

Using Sleepycat's version 3.2.9 compiled with 1.85 support works fine, you
don't need to install a separate copy of version 1 to compile 2.4.3.
However, I had to make the following patch:
