Have you looked at my work in 
https://bitbucket.org/timosi/minlibd/src/master/
There is my libdruntime port and working sample program for stm32.

Tdata and tbss are handled special way in linker. They seem to be 
there but actually they are not. Look at 
https://bitbucket.org/timosi/minlibd/src/master/tools/stm32f4/ldscript for my workaround.

I have not updated this project for a while although I have half 
ready version for gcc 11. There are issues with exceptions that I 
have not been able to fix.

There is documentation in the directories and also in the wiki. 
Feel free to contact me if you want to ask something.
