In tools/v2/build/engine/build.bat:

if --guess-toolset in $argv
  call :Guess_Toolset
  return $BOOST_JAM_TOOLSET

Also, make sure that local variables don't escape.
I don't know how to pass the return value through setlocal.

(I just noticed this in bootstrap.bat:
REM Ideally, we should obtain the toolset that build.bat has
REM guessed. However, it uses setlocal at the start and does not
REM export BOOST_JAM_TOOLSET, and I don't know how to do that
REM properly. Default to msvc for now.)

in bootstrap.bat:

TOOLSET = find argument --with-toolset=xxx
if not $TOOLSET
  set TOOLSET=`tools/build/v2/engine/build.bat --guess-toolset`
