Re: [PATCH v2 02/16] powerpc: override __ALIGN() and __ALIGN_STR() macros

Powerpc instructions must be word-aligned. Currently,
there is an alignment of 16 bytes (by default), and it is
much more than what is required for powerpc (4 bytes).

The default expansion of __ALIGN() macro is:
#define __ALIGN       .align 4,0x90

Since Powerpc Linux does not require a 16 byte alignment,
override __ALIGN() and __ALIGN_STR() macros to use required
4 byte alignment.
