"info shared".  Maybe strace GDB to see what it's opening and whether
it fails to find any files.

libthread_db.so is necessary to debug threads.  It has to be on your
target (sounds like it is) and it has to be able to initialize; worry
about this after you've figured out whether GDB loaded shared
libraries, because it will not be able to initialize unless GDB can
load an unstripped copy of libpthread.so.
