编译OpenJDK8：configure: Could not compile and link with freetype. This might be a 32/64-bit mismatch.

　　具体错误：

checking if we can compile and link with freetype... no
configure: Could not compile and link with freetype. This might be a 32/64-bit mismatch.

　　之前遇到同类问题：

　　检查了一下，确认库是６４位的，怎么又出现了？于是检查了报错位置：

    # Try to compile it
    { $as_echo "$as_me:${as_lineno-$LINENO}: checking if we can compile and link with freetype" >&5
$as_echo_n "checking if we can compile and link with freetype... " >&6; }

          #include
          #include FT_FREETYPE_H
          int main () {
            FT_Init_FreeType(NULL);
            return 0;
          }

          { $as_echo "$as_me:${as_lineno-$LINENO}: Could not compile and link with freetype. This might be a 32/64-bit mismatch." >&5
$as_echo "$as_me: Could not compile and link with freetype. This might be a 32/64-bit mismatch." >&6;}

　　这里意思是检查一下库是否正常。库肯定正常，那就是头文件有问题？这个头文件为了在ＭＡＣ上编译，加了几个包含。于是进行了反复测试，原来是包含的unistd.h导致。
