问题现象： MIPS64 Architecture平台UOS V20 104x版本安装编译LTP 20200515版本，make阶段报错，报错信息如下： - In file included from ../../../../include/tst_test.h:14,
- from ustat01.c:9:
- **/usr/include/mips64el-linux-gnuabi64/sys/ustat.h:33**:12: error: conflicting types for ‘statfs’
- extern int ustat (__dev_t __dev, struct ustat *__ubuf) __THROW;
- ^~~~~

glibc 2.28的发行说明说：
The obsolete function ustat is no longer available to newly linked binaries; the headers and have been removed. This function has been deprecated in favor of fstatfs and statfs. 根据报错提示修改/usr/include/mips64el-linux-gnuabi64/sys/ustat.h文件，注释掉第33行（extern int ustat (dev_t dev, struct ustat *ubuf) THROW;） 解决方法： 在make之前需要修改2处的ustat.h头文件信息
1、/usr/include/mips64el-linux-gnuabi64/sys/ustat.h文件注释掉第33行
2、/usr/include/mips64el-linux-gnuabi64/bits/ustat.h文件注释掉第24-30行
