Well, let's take this example. The user has generated a filesystem
on a flash, and is now debugging something natively (which is already
somewhat unlikely), and there is no writeable FS in sight.

Chances are, there is no libthread_db.so.1 anywhere in sight either.
If there is one, the user could use it by setting
libthread-db-search-path to containing directory.

The only case your proposal fixes is when libthread_db.so.1 *is*
present on the system, but for some mysterious reason is called
libsomething_else.so instead.

Under what realistic conditions would this happen?
