用arm-none-eabi-gcc编译STM32F10x

对于ubuntu 14.04（我的是14.10），官方仓库里就有适用的交叉编译器

apt-get install gcc-arm-none-eabi

对于较低的版本，可以使用https://launchpad.net/gcc-arm-embedded/提供的二进制压缩包，

以及https://launchpad.net/~terry.guo/+archive/ubuntu/gcc-arm-embedded提供的软件源

add-apt-repository ppa:terry.guo/gcc-arm-embeddedapt-get updateapt-get install gcc-arm-none-eabi

以下是项目的makefile，CMSIS中核心支持使用2.00版本，硬件支持使用3.5版本，外设驱动为3.5版

makefile使用find找到所有.c和.s文件，根据自动依赖进行编译。编译出来的文件，根据stm32_f103ze_gcc.ld生成.bin和.hex文件
