The @code{set print symbol-loading} command allows you to enable or
disable printing of messages when @value{GDBN} loads symbols.
By default, these messages will be printed, and normally this is what
you want. Disabling these messages is useful when debugging applications
with lots of shared libraries where the quantity of output can be more
annoying than useful.
