#9485: stdout and stderr not forwarded to respective channels

 Apparently, Boost.Build does not forward output sent out by commands it
 executes to respective channels to which the output is originally sent by
 executed commands.

 Simple test on Linux seems to prove that:

 {{{
 $ cat Jamroot
 exe testcpp : test.cpp ;
 $ cat test.cpp
 X main() {}
 $ b2 1>/dev/null
 $ b2 2>/dev/null
 ...found 7 targets...
 ...updating 2 targets...
 gcc.compile.c++ bin/gcc-4.8.2/debug/test.o
 test.cpp:1:1: error: ‘X’ does not name a type
  X main() {}
  ^

     "g++"  -ftemplate-depth-128 -O0 -fno-inline -Wall -g -fPIC     -c -o
 "bin/gcc-4.8.2/debug/test.o" "test.cpp"

 ...failed gcc.compile.c++ bin/gcc-4.8.2/debug/test.o...
 ...skipped <pbin/gcc-4.8.2/debug>testcpp for lack of
 <pbin/gcc-4.8.2/debug>test.o...
 ...failed updating 1 target...
 ...skipped 1 target...
 $
 }}}

 I've observed the same channel merging in [https://github.com/mloskot/qt-

 creator-plugin-boostbuild Boost.Build Plugin for Qt Creator] that I have
 been developing.

 I asked on IRC about it, and Volodya confirmed channels should not be
 merged:
 {{{
 <volodya> mloskot: I think children stdout and stderr should be forwarded
 to stdout and stderr respectively.
 }}}

 So, I think it is a bug.
