If I grok the binutils documentation, this patch breaks the official ARM 
assembler syntax:

".align expression [, expression]
This is the generic .align directive. For the ARM however if the first 
argument is zero (ie no alignment is needed) the assembler will behave as if 
the argument had been 2 (ie pad to the next four byte boundary). This is for 
compatibility with ARM's own assembler."
