If You don't find any cpp module property, e.g. linkerFlags for abuse, You
could write a shell wrapper script as a replacement for nios2-g++. That
script calls nios2-g++ and either inserts -msys-crt='crt0.o' hardcoded
before passing the others arguments or re-arranges all command line
arguments according to Your needs. In the latter case You provide
-msys-crt=XY via cpp.linkerFlags and use the wrapper script to move it to
the desired position.
You have to adjust cpp.linkerName and cpp.linkerPath according to Your
script's name and location.
