[GDBSERVER] make gdbbuild exit on error

If an error occurs, such as wget failing because the site (or proxy)
is unavailable, the script will now terminate, rather than trying
to soldier on without any real hope of success.

mkbuildtree should really get the same treatment, but that
can wait for another day.
