Issue fixing

`elf.h` file not found

~~安装homebrew 安装libelf brew install libelf~~ 拷贝 elf.h (二选一，两个都行)

GitHub
/Volumes/android/aosp/external/elfutils/libelf/elf.h，遇到了features.h文件未找到的错误，就将#include <features.h> 一行注释掉。将 elf.h 拷贝到 /usr/include 或者 /usr/local/include 中，推荐放在后者，放在前者的话系统升级时会覆盖。目前发现 libelf 不需要。

`byteswap.h` file not found

In file included from arch/x86/tools/relocs_32.c:1:
arch/x86/tools/relocs.h:13:10: fatal error: 'byteswap.h' file not found
#include <byteswap.h>
         ^
1 error generated.
make[1]: *** [arch/x86/tools/relocs_32.o] Error 1

解决：拷贝对应文件夹中的头文件

arch/x86/kernel/cpu/capflags.c:69:31: error: expected expression before ']' token

[X86_FEATURE_PCLMULQDQ (432+] = "pclmulqdq (432+”, 等这一个C文件里的错误。

根据Linux的github里面的sh脚本，这个文件应该是根据 arch/x86/kernel/cpu/mkcapflags.sh /Volumes/android/x86_64/arch/x86/include/asm/cpufeature.h 和生成的。

解决：拷贝对应文件夹中的capflags.c

下载 `GNU sed` 和 `stat`

起初未替换sed 和stat，内核编译好了，启动不了

brew install gnu-sed coreutils

设置环境变量PATH 按照上述安装命令中生成的提示信息设置PATH
