I'm trying to use Coverity Scan with an embedded application written in C++17 (ARM GCC Embedded v7.2). The application itself builds well and error/warning-free; however, the Coverity Scan Self-Build tool (cov-analysis-linux64-2017.07, the latest) fails to compile certain C++ files with the following error (abridged):
[19888] EXECUTING: /home/pavel/opt/gcc-arm-none-eabi/bin/../lib/gcc/arm-none-eabi/7.2.1/../../../../arm-none-eabi/bin/as -I . -I src -I src/os_config -I eigen -I senoval -I legilimens -I popcop/c++ -I build/current_build_info -mcpu=cortex-m4 -mfloat-abi=hard -mfpu=fpv4-sp-d16 -meabi=5 -alms=build/lst/ch.lst -o build/obj/ch.o /tmp/ccK73Qaa.s

As can be seen, the build tool did not pass the option -std=c++17 to the assembler. By the way, the application's own build system does not make direct calls to the assembler; the Self-Build tool does it on its own. This is how the Coverity Self-Build process is configured:
cov-configure --comptype gcc --compiler arm-none-eabi-gcc --template
make clean
cov-build --dir build/cov-int make -j8
cd build
tar czvf coverity.tgz cov-int
How do I configure the Self-Build tool to build C++17 code correctly?
