It ended up that the easiest way to support what you want was to extend 
testing.jam slightly.

It is now possible to pass in dependent targets as input files to test 
run targets. Or in English.. You can specify things like <dll>something 
in the "input-files" argument of "run" and "run-fail" tests. The 
dependency will get built and the resulting full paths to the files 
passed as arguments to the test. I added an example, which is what I 
used to test the functionality, in 
[boost-root]/tools/build/v1/example/target_test_arg.

One caveat to be aware of is that on certain platforms, i.e. Windows, 
some targets (DLLs) generate more than one file and *all* files are 
passed to the test. Which for the example above means it outputs 
something akin to:

====== BEGIN OUTPUT ======
arg #0 = 
'C:\Boost\test\bin\boost\tools\build\v1\example\target_test_arg\simple.test\cw-8_3\debug\threading-multi\simple.exe'
arg #1 = 
'C:\Boost\test\bin\boost\tools\build\v1\example\target_test_arg\simple.dll\cw-8_3\debug\threading-multi\simple.dll'
arg #2 = 
'C:\Boost\test\bin\boost\tools\build\v1\example\target_test_arg\simple.dll\cw-8_3\debug\threading-multi\simple.lib'
arg #3 = 
'C:\Boost\test\bin\boost\tools\build\v1\example\lib_use\libsimple.lib\cw-8_3\debug\threading-multi\libsimple.lib'
arg #4 = 
'C:\CVSROOTs\Boost\boost\tools\build\v1\example\target_test_arg\simple_lib.cpp'

EXIT STATUS: 1
====== END OUTPUT ======

So your test program will have to sort out which of the two files is the 
shared library.

Enjoy.
