> 2. IS_BUILTIN.tcp_wrappers will tell you if a builtin has been detected.

i86:

$ bmake show-var VARNAME=IS_BUILTIN.tcp_wrappers
no

sparc:

$ bmake show-var VARNAME=IS_BUILTIN.tcp_wrappers
yes


> 3. USE_BUILTIN.tcp_wrappers will tell you if the builtin will be used.

identical to IS_BUILTIN


I have tried different debug options of bmake some time ago, but none 
would help (in a way I am aware of) to understand the flow of 
information and to see, at which point things start to diverge.
