No entry point was defined, so it defaulted to the beginning of the .text output section where the vector table is located by default in Contiki. Actually, the vector table may be located elsewhere, and the ROM-based boot loader first reads the CCA to find the vector table. Consequently, this commit sets the entry point to the CCA, which fixes both the entry point and the initial symbol reference, so this commit also removes the now-unneeded "__used__" and "KEEP" keywords from the CCA.
