openrisc: Add _text symbol to fix ksym build error

Browse Source 
[ Upstream commit 086cc1c31a0ec075dac02425367c871bb65bc2c9 ]

The build robot reports:

   .tmp_kallsyms1.o: In function `kallsyms_relative_base':
>> (.rodata+0x8a18): undefined reference to `_text'

This is when using 'make alldefconfig'. Adding this _text symbol to mark
the start of the kernel as in other architecture fixes this.
