In a subsequent patch, we would want to annotate powerpc assembly functions with SYM_FUNC_START_LOCAL macro. This macro depends on __ALIGN macro.
The default expansion of __ALIGN macro is: #define __ALIGN .align 4,0x90 So, override __ALIGN and __ALIGN_STR macros to use the same alignment as that of the existing _GLOBAL macro. Also, do not pad with 0x90, because repeated 0x90s are not a nop or trap on powerpc.
