Hi @probinson thanks for pointing out the way, agree with this new solution. 
After checking the codes, I found there are already `-gstrict-dwarf`, 
`-gno-strict-dwarf` options in clang code base, but there seem no users of 
them. Do you happen to know the story of these two options? I get a quick 
search, no clue yet. Can we reuse these options for the intention here. Thanks?
