[OE-core] [PATCH] binconfig-disabled: write an message to stderr to help confused developers

[Ross Burton]

Often configure scripts or Makefiles that use the stub scripts written by
binconfig-disabled fail mysteriously with no obvious problem.  Attempt to solve
this by writing an error to stderr which hopefully makes it to the logs.
