I erroneously interrupted the build on my Atom CPU (actually it
took me a while to figure out that I should specify option
--no-parallel to dh avoid the drive thrashing like hell and
ultimately OOM conditions mid-way during the build, hence the
delay).  I'm about to restart a run:
  - without patches mentioned earlier,
  - with -msse replacing -fstore-float in i386 specific build
    options,
  - with ccache, so I gain some checkpoints if I screw the build
    again.

Hope it will reveal something interesting, but count some days
to it.  Maybe a virtual machine would be faster in this case;
1 GiB of RAM is considered quite light nowadays.

Kind Regards,
