Using built-in specs.

COLLECT_GCC=./gcc

COLLECT_LTO_WRAPPER=/root/test/usr/bin/../libexec/gcc/aarch64-linux-gnu/10.3.1/lto-wrapper

Target: aarch64-linux-gnu

Configured with: ../configure --prefix=/usr --mandir=/usr/share/man --infodir=/usr/share/info --enable-shared --enable-threads=posix --enable-checking=release --with-system-zlib --enable-__cxa_atexit --disable-libunwind-exceptions --enable-gnu-unique-object --enable-linker-build-id --with-linker-hash-style=gnu --enable-languages=c,c++,fortran,objc,obj-c++,lto --enable-plugin --enable-initfini-array --disable-libgcj --with-isl --without-cloog --enable-gnu-indirect-function --build=aarch64-linux-gnu --with-stage1-ldflags=' -Wl,-z,relro,-z,now' --with-boot-ldflags=' -Wl,-z,relro,-z,now' --disable-bootstrap --with-multilib-list=lp64 --enable-bolt

```

**【问题复现步骤】**

1.安装gcc,g++,dejagnu

```

yum install gcc g++ dejagnu -y

```

2.在gcc-10.3.0/gcc/testsuite目录下新建site.exp文件如下：

```

set GXX_UNDER_TEST "g++"

set CFLAGS_FOR_TARGET "-Wl,-rpath=/usr/lib64"

```

3.到gcc-10.3.0/gcc/testsuite目录执行以下命令：

```

runtest --tool g++ tree-ssa.exp=loop-crc*

```

**【实际结果】**

3.到gcc-10.3.0/gcc/testsuite目录执行以下命令：

```

runtest --tool g++ tree-ssa.exp=loop-crc*

```

**【实际结果】**


set GXX_UNDER_TEST "g++"

set CFLAGS_FOR_TARGET "-Wl,-rpath=/usr/lib64"

```

-Wl,-rpath指向转测工具链的lib64

3.到gcc-10.3.0/gcc/testsuite目录执行以下命令：

```

runtest --tool g++ tree-ssa.exp=loop-crc*

```

**【实际结果】**
