Subject: ldd: define the "unused" variable
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=13d67746cbe1273afaf6b9de9d6065ab76ee7697;p=thirdparty%2Fglibc.git

ldd: define the "unused" variable

The "unused" variable could be use unitialized, which is an issue if ldd
is ran with "-u". Fix that by defining the variable to an empty value,
just like it is already done for the bind_now, warn and verbose
variables.
