I just built each library separately, and the results are enlightening.

Based on the list of libraries that b2 prints the building/not building 
status for, these are all results that are different from what I 
expected to get:

- coroutine2: No statics, DLL for context, no output for coroutine2

- metaparse: Statics for chrono, system, timer, unit_test_framework,
              no output for metaparse

- test: Statics and DLLs for chrono, system, test_exec_monitor, timer,
         DLLs for prg_exec_monitor, unit_test_framework,
         no output explicitly named "test"

I did not attempt python, and had no build activity for mpi and 
graph_parallel, which is clearly due to missing external dependencies.

However, I found the culprit, and it looks like I've been chasing wild 
geese all the time. test has a dependency on timer, which pulls in 
chrono and system. Building --without-test gives, at last, the expected 
result.

Anyway, libs/metaparse/build/Jamfile.v2 looks like it may not be meant 
to be used when building all libraries, and I think there is something 
wrong with coroutine2 also; its config.hpp and Jamfile.v2 do not seem 
quite clear on whether it is "coroutine" or "coroutine2" or 
"couroutines2". But I'm just guessing here.
