When -ffunction-sections or -fdata-section are used, symbols are placed into sections such as .data.eserial1_device and .bss.serial_current. Update the linker script to explicitly include these. Without this change (at least with my gcc-4.5.3 built using crosstool-ng), I see that the sections do end up being included, but __bss_end__ gets set to the same value as __bss_start.
