[Boost-build] BUG intel toolset causes ambiguity in <file> prebuilt library

I mentioned this on an old thread, but I am afraid it might be buried and 
not noticed so I decided to write up a new description of the problem.

Using CVS HEAD of BB and intel-linux 8 toolset, prebuilt <file> targets 
cause BB to fail stating there is an ambiguity between the intel generator 
and the builtin one.

Vlad fixed this a while back for <name>ed system libraries by adding a 
generators.override to the searched-lib-generator.

There is another line just above that fix that states:
    generators.override builtin.lib-generator : intel-linux.prebuilt ;

And I am wondering if it might be a typo. Shouldn't it be:
    generators.override builtin.prebuilt : intel-linux.prebuilt ;

I have attached a modifed version of the Jamroot from the 
"examples/libraries" example that demonstrates the problem.
If you perform a "bjam fubar" to create the .a file then "bjam app2" to try 
to link against it you should get the ambiguity error.
Changing the line above fixes that but I don't know if it might cause 
trouble elsewhere (Although I haven't seen such trouble so far).
