The standard way for the l4re build system to link against certain 
libraries ist to put them in the REQUIRED_LIBS list.

So just change

REQUIRES_LIBS            = cxx_libc_io cxx_io

to

REQUIRES_LIBS            = cxx_libc_io cxx_io libstdc++

And it compiles fine. Do not forget to also link against 
libc_be_file_stdin (in the same way as above) if you want to have 
keyboard interactions.

Best regards
