Here is some “workaround” for this my problem (in case someone else will need). What I was doing after compilation was crashing, is
make clean
and then make or make -j1. Now I just found aforementioned file
GlobalISelEmitter.cpp.o
and just deleted it, then I rebooted PI and run make (accidentally , without -j1 option) and voila
[ 21%] Building CXX object interpreter/llvm-project/llvm/utils/TableGen/CMakeFiles/obj.llvm-tblgen.dir/CTagsEmitter.cpp.o
[ 22%] Built target obj.llvm-tblgen
[ 22%] Linking CXX executable ../../bin/llvm-tblgen
[ 22%] Built target llvm-tblgen
Thanks for the clue and your help
