X1000: x1000_ram.lds: 修复调试时崩溃的问题/Fix crash when debugging.

当ELF文件包含很多gnu_extab*开头的section时(>100)，会导致GDB在加载操作
时崩溃。通过创建一个section来对以该名称开头的所有section进行分组可以
解决该问题。

When ELF contains many sectios(>100) starting with name gnu_extab*,
will causing GDB to crash on load action. Solving the problem by
creating a section to group all sections which begin with that name.
