I don't know awk, so that looks very impressive to me!  I think it's a
good idea to fix them once and for all.

It would be worth grepping for gdb_reinitialize_dir, to catch more spots
that can be changed.  For example, in gdb.base/overlays.exp we have the
sequence without gdb_exit:

 49 gdb_start
 50 gdb_reinitialize_dir $srcdir/$subdir
 51 gdb_load ${binfile}

Those can also be changed with clean_restart.
