----------------------------------
SDCC的版本7102到8719存在问题，最新可用的版本为8737（截止2014年4月）
--------------------------------
1. 修改 /opt/sdcc/device/lib/incl.mk
将最后一行
MODELS = small medium large
替换为
MODELS = small large huge
2. 修改 /opt/sdcc/device/lib/incl.mk
将某行
TARGETS += models small-mcs51-stack-auto
替换为
TARGETS += models model-mcs51-stack-auto
3. 仅支持8051，禁止对其他MCU的支持
./configure --disable-gbz80-port --disable-z80-port --disable-ds390-port \
--disable-ds400-port --disable-pic14-port --disable-pic16-port \
--disable-hc08-port --disable-r2k-port --disable-z180-port \
--disable-sdcdb --disable-ucsim
-----------------------------------------------------
以上操作没有验证。
