Subject: [PATCH] kbuild/builddeb: Fix !CONFIG_GCC_PLUGINS build

From: Borislav Petkov <bp@...e.de>

When building a bindeb-pkg target into an object output dir, i.e., O=, I
get:

  find: `scripts/gcc-plugins': No such file or directory
  /mnt/kernel/kernel/linux-2.6/scripts/package/Makefile:97: recipe for target 'bindeb-pkg' failed
  make[3]: *** [bindeb-pkg] Error 1
  /mnt/kernel/kernel/linux-2.6/Makefile:1310: recipe for target 'bindeb-pkg' failed
  ...

Check whether CONFIG_GCC_PLUGINS is enabled before collecting .so plugin
names.
