修改components\toolchain\gcc中的Makefile.common文件里的toolchain中的編譯工具，因?yàn)榘惭b的arm-none-eabi路徑與“Makefile.posix”中定義的不一致。

# Toolchain commands
CC      := $(call quote,$(GNU_PREFIX)-gcc)
CXX     := $(call quote,$(GNU_PREFIX)-c++)
AS      := $(call quote,$(GNU_PREFIX)-as)
AR      := $(call quote,$(GNU_PREFIX)-ar) -r
LD      := $(call quote,$(GNU_PREFIX)-ld)
NM      := $(call quote,$(GNU_PREFIX)-nm)
OBJDUMP := $(call quote,$(GNU_PREFIX)-objdump)
OBJCOPY := $(call quote,$(GNU_PREFIX)-objcopy)
SIZE    := $(call quote,$(GNU_PREFIX)-size)
#CC      := $(call quote,$(GNU_INSTALL_ROOT)$(GNU_PREFIX)-gcc)
#CXX     := $(call quote,$(GNU_INSTALL_ROOT)$(GNU_PREFIX)-c++)
#AS      := $(call quote,$(GNU_INSTALL_ROOT)$(GNU_PREFIX)-as)
#AR      := $(call quote,$(GNU_INSTALL_ROOT)$(GNU_PREFIX)-ar) -r
#LD      := $(call quote,$(GNU_INSTALL_ROOT)$(GNU_PREFIX)-ld)
#NM      := $(call quote,$(GNU_INSTALL_ROOT)$(GNU_PREFIX)-nm)
#OBJDUMP := $(call quote,$(GNU_INSTALL_ROOT)$(GNU_PREFIX)-objdump)
#OBJCOPY := $(call quote,$(GNU_INSTALL_ROOT)$(GNU_PREFIX)-objcopy)
#SIZE    := $(call quote,$(GNU_INSTALL_ROOT)$(GNU_PREFIX)-size)

然后就可以通過make進(jìn)行編譯：
