MPS2_AN385 improvements (#1225)

Browse Source 
* MPS2_AN385 improvements

Sync various MPS2_AN385 CORTEX-M3 QEMU targets and improve their
Makefiles and cleanup gcc support:
- FreeRTOS-Plus/Demo/FreeRTOS_Plus_TCP_Echo_Qemu_mps2:
  - Makefile
    - output image size after linking
    - move -nostartfiles from compiler to linker flags
    - modernize compiler warning flags
    - add --gc-sections to linker flags
  - TCPEchoClient_SingleTasks.c: fix compiler warnings
  - main.c: fix compiler warnings (remove unused code)
  - main_networking.c
    - remove ipLOCAL_MAC_ADDRESS (unknown)
    - fix compiler warnings about unused params
  - startup.c: main(void), remove unused includes,
    silence  unused params
  - syscalls.c: remove unused defines, silence unused params,
    more compact _sbrk()
- FreeRTOS/Demo/CORTEX_MPS2_QEMU_IAR_GCC/build/gcc:
  - Makefile
    - CFLAGS/LDFLAGS in more readable lines
    - move -nostartfiles to linker flags
    - comment out -specs=rdimon.specs as it is not needed
  - startup_gcc.c: fix typo in comment, remove unused uart code
- FreeRTOS/Demo/CORTEX_MPU_M3_MPS2_QEMU_GCC
  - Makefile
    - after compilation output size of image
    - remove -DQEMU_SOC_MPS2, not needed
    - update many CFLAGS/LDFLAGS settings to more modern gcc/source
    - -ffunction-sections -fdata-sections is moved to CFLAGS
  - startup.c: sync with other ports
  - syscall.c: _write(): param buf is not unused, silence unused params
