构建系统可以选择Windows (mingw-w64-i686) hosted cross compilers或x86_64 Linux hosted cross compilers

目标平台如下表格

目标平台
AArch32 bare-metal target (arm-none-eabi)	aarch32 裸板
AArch32 target with hard float (arm-linux-none-gnueabihf)	aarch32 linux 包含浮点数
AArch64 ELF bare-metal target (aarch64-none-elf)	aarch64 裸板
AArch64 GNU/Linux target (aarch64-none-linux-gnu)	aarch64 linux
AArch64 GNU/Linux target (aarch64_be-none-linux-gnu)	aarch64 linux 大端字节序

配置conan构建profile
