staging: usbip: userspace: allow `configure --with-tcp-wrappers` (ce591f76) · Commits · 戴 / test

When `--with-tcp-wrappers` is passed to `configure`, the previous code always reset LIBS to $saved_LIBS, regardless of whether libwrap was found or not. The current code makes the `--with-tcp-wrappers` case look more like the default case, and it only resets LIBS if libwrap was not found. Signed-off-by:
