I have also set them in `.bashrc`.

But when developer provides `--enable-fsanitize-asan` to `./configure` we 
enable `-fsanitize=address`. And `-fsanitize=address` can optionally detect 
stack use after return problems if 
`ASAN_OPTIONS=detect_stack_use_after_return=1`. So why not mention that in 
`./configure --help` along side "--enable-fsanitize-asan Turn on Address 
Sanitizer"?

Of course, we can also document this in wiki but I doubt a dev will read 
anything beyond `./configure --help` to know and figure out how to activate the 
sanitizer for wget2...
