HP gnu source-level debugger 5992-4701 - Manual (Page 369)

--norecursion Configure only the directory level where configure is
executed; do not propagate configuration to subdirectories.
--target=target Configure GDB for cross-debugging programs running on
the specified target. Without this option, GDB is configured
to debug programs that run on the same machine (host) as
GDB itself. There is no convenient way to generate a list of
all available targets.
host ... Configure GDB to run on the specified host. There is no
convenient way to generate a list of all available hosts.
There are many other options available as well, but they are generally needed for special
purposes only.
