smartalign.mac: align macro should align a segment as well

This change may have backward compatibility issue but
most probably the sane program never used sections with
base address less then instruction alignment.

Note that alignment may only increase which means if a
section is aligned on 2^5 the align 2^4 will not affect
the section.
