.uleb128 vs .align

[Richard Henderson <rth at redhat dot com>]

	.section	.data,"aw",@progbits
	.align 3
 	.uleb128 0xf
	.align 3
	.4byte	foo

This would do the wrong thing on Alpha, because it would think
that the second .align directive wasn't needed.  (This comes
from trying to emulate OSF/1 auto-alignment crap, and if we 
don't suppress redundant alignments we wind up with one piece
of data per fragment, which is incredibly wasteful.)

Fixed thus.
