In the --help text, print the actual name of the GDB that will by
default be used.  Fixes #151938.  Unfortunately this makes the help
text non-constant, which could have a bad effect on regtesting; but
GDB is so usually installed in the standard place /usr/bin/gdb that I
don't think that's much of a big deal.
