Huh.  I was tricked.  The gcc-11 command line I showed was exactly
what I ran, without what I'd normally add, -o pr28149.  So a.out
output.  Under those circumstances it seems gcc writes temp files to
a-pr28149.*, and I looked at the old pr28149.s.

Eh well, I may not have made the gas dwarf cleanup if I'd known the
problem was fixed already by gcc changes..
