Commit: --rosegment: Restore alignment of text segment

[Nick Clifton]

Hi Guys,

  *sigh* I have found another snafu with my --rosegment feature.
  I had disabled the alignment of the text segment in the on-disk
  image, on the assumption that the loader would be able to load
  a partial page into memory.  In turns out however that this is
  not correct, and that data following the text segment in the
  on-disk image can be loaded into the executable segment in
  memory.

  So I am checking in this patch to restore the alignment of the
  text segment in the on-disk image.  Which means that the file
  size increase when using '-z separate-code' is not alleviated
  as much. (It can still be slightly improved since --rosegment
  reduces the number of data segments).

Cheers
  Nick
