I have tried to do it in the project target too but found no syntax to 
do it. There is another option however (and it is documented).

To link with ATLAS (optimised BLAS libraries), I added to my 
user-config.jam following:

<quote from user-config.jam>
import project ;
project.initialize $(__name__) ;
project user-config ;
lib blaslib : : <name>atlas <search>/usr/local/lib ;
</quote>

In my Jamfile I now write

<quote from Jamfile>
exe foo : bar.cpp /user-config//blaslib ;
</quote>

This should work IF you only have one library per prebuilt lib. Let me 
explain: For linking with atlas, you actually need to link with three 
libraries in a specific order: libf77blas.a, lilbcblas.a and libatlas.a.
Now with the above mechanism you can not associate multiple external 
libraries with one prebuilt-library (blaslib) AFAICT ;-( Or is there ?
