the comment at the start of the file tools/build/gcc-tools.jam says:
# The name by which g++ is invoked. You can also use this in
# lieu of setting the <cxxflags> property to force options such
# as "-V3.0.4" into the g++ command line: "-sGXX=g++ -V3.0.4".
However, gcc-C++-action starts with
$(.GXX:R=$(GCC_BIN_DIR)) -c -Wall
If bjam is invoked with -sGXX=g++ -V3.0.4" -sGCC_BIN_DIRECTORY=/foo
then GCC_BIN_DIR gets inserted in front of every element of $(GXX).
This results in the command line /foo/g++ /foo/-V3.0.4 -c -Wall ...
