linux-tools (3.2.17-1) usbip-fix-explicit-configure-with-tcp-wrappers.patch

From: Ben Hutchings <ben@decadent.org.uk>
Subject: usbip: Fix explicit configure --with-tcp-wrappers

If the --with-tcp-wrappers[=yes] option is given and the wrap library
checks out, we currently add '-lwrap' to $LIBS but then reset it to
$saved_LIBS.  In fact there is no need to save and restore $LIBS here
because failure is fatal.  $wrap_LIB is also unused, so don't set that
either.
