The term gdb-client is deceptive - although it parallels the gdb-server name,
it is actually a full fledged gdb version. I want to use it to debug uClibc
core files on my host system. Although I haven't got that to work yet, I wasted
time figuring out how to do build gdb for the host not realizing it already had
a target. With this documentation change, things would have been a lot clearer
to me.
