编译node-v4.2.1，出现错误：undefined reference to getpwuid_r

error: undefined reference to 'getpwuid_r'

我的解决方法（使用getpwuid替换getpwuid_r）：
[root@localhost node-v4.2.1]# grep getpwuid_r -R .
[root@localhost node-v4.2.1]# gedit ./deps/uv/src/unix/core.c
将
    r = getpwuid_r(uid, &pw, buf, bufsize, &result);
替换为：
    //r = getpwuid_r(uid, &pw, buf, bufsize, &result);
    result = getpwuid(uid);  
    if(result == NULL) r = 0;

Answer 1：The API level in our build script was recently raised to 21, closing. If you need support for an API level < 21, a patch would be welcome

Answer 2：There is no getpwuid_r implementation in bionic libc in Android platforms below 19. Just remove the call off the code.
