Comment (by Chris Johns):

 I think the simplest solution is to:

 1. Leave `libbsd.py` as is for now. I feel this file can be split into
 parts after an initial refactoring has been completed.

 2. Create `waf_libbsd.py` which is a copy of `libbsd_waf.py` and convert
 all the `self.add('')` calls into actual code. I thnk `freebsd-to-
 rtems.py` can use the `builder.py` base class because all it needs to call
 is `processSource()` which is all in `builder.py`.

 3. Add class methods to match the required `waf` functions:
  a. `init`
  b. `options`
  c. `bsp_configure`
  d. `configure`
  e. `build`

 4. Update `wscript` to create a `Modules` instance and hold globally. It
 then uses it for each of it's calls.

 5. Update `freebsd-to-rtems.py` to use `waf_libbsd.py` and remove the
 generate code.

 This conversion is not too difficult. The INI configuration support can be
 built on opt of this. The result is:

 a. List of modules to build
 b. Defines
 c. Compile flags
