MIPS64 平台UOS V20 104x版本安装编译LTP 20200515报错解决方法

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：

1. In file included from ../../../../include/tst_test.h:14,
2. from ustat01.c:9:

复制代码

原因分析：

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
