Looks like gdb has a `set debuginfod verbose on/off` setting for this. There's
also the generic `DEBUGINFOD_VERBOSE` environment variable. If set, this
triggers remote logging to stderr.
The environment variable is something we generally want to support for
debuginfod lookups; that could probably safely live in the debuginfod client
library itself, as it does with libdebuginfod. If LLDB had its own setting for
this, it may be able to invoke a setter in the client library, but current
everything in the client library is global, so there may be some threading
gotchas there.
For reference, here's the gdb settings for debuginfod:
https://sourceware.org/gdb/current/onlinedocs/gdb.html/Debuginfod-Settings.html
And the environment variables:
