The simple hello example in bbv2 works fine for me <
https://github.com/boostorg/build/tree/develop/example/hello>:

===
Coqui:hello grafik$ b2 toolset=emscripten -d+2
common.mkdir bin

        mkdir -p "bin"

common.mkdir bin/emscripten-1.36.5

        mkdir -p "bin/emscripten-1.36.5"

common.mkdir bin/emscripten-1.36.5/debug

        mkdir -p "bin/emscripten-1.36.5/debug"

emscripten.compile.c++ bin/emscripten-1.36.5/debug/hello.bc

    "/Developer/Tools/emscripten/emscripten/tag-1.36.5/emcc" -x c++ -O0
-fno-inline -Wall -g4 -s DEMANGLE_SUPPORT=1   -c -o
"bin/emscripten-1.36.5/debug/hello.bc" "hello.cpp"

emscripten.link bin/emscripten-1.36.5/debug/hello.js

    "/Developer/Tools/emscripten/emscripten/tag-1.36.5/emcc"   -o
"bin/emscripten-1.36.5/debug/hello.js"
"bin/emscripten-1.36.5/debug/hello.bc"        -O0 --llvm-lto 0 -g4 -s
DEMANGLE_SUPPORT=1

warning: emitted code will contain very large numbers of local variables,
which is bad for performance (build to JS with -O2 or above to avoid this -
make sure to do so both on source files, and during 'linking')
Coqui:hello grafik$ node ./bin/emscripten-1.36.5/debug/hello.js
Hello!
Coqui:hello grafik$

Try that one.
