Added a test case for moving CORE_LIB in PR #583.

This patch is meant to test the link order, if the OTHER_OBJS
variable gets used to add 3rd party archives, that depend on the
Arduino core lib (the archive pointed to by the CORE_LIB variable).

The examples/Blink3rdPartyLib directory contains a stripped down Blink
and includes a library in the examples/Blink3rdPartyLib/Toggle
sub-directory. The archive, built inside the Toggle directory mimics a
3rd party library. The archive gets built and linked in by using the
OTHER_OBS variable in examples/Blink3rdPartyLib/Makefile.

+# This is an example Makefile, that demonstrates the linking of a third party
+# library. In this case the third party library resides in the ./Toggle
+# sub-directory. Note that the archive TOGGLE_ARCHIVE _only_ contains the
+# compiled Toggle.c.o object. The TOGGLE_ARCHIVE is thus very lean, but it
+# requires the Arduino libraries, which are being build in this directory,
+# together with Blink, the 'main' program.
