Ah! I finally have a progress bar that doesn't stall the build!
- pipe size in Linux is only 8*512=4096 bytes
- pipe size is not setable
- when the feeding process spits out data faster than the eating
process can read it, then the feeding process stalls after 4KiB
of data sent to the pipe
- for us, the progress bar would spawn a sub-shell every line,
and the sub-shell would in turn spawn a 'date' command.
Which was sloooww as hell, and would cause some kind of a
starvation: the pipe was full most of the time, and the
feeding process was stalled all this time.

Now, we use internal variables and a little hack based onan offset
to determine the elapsed time. Much faster this way, but still
CPU-intensive. 
     1 Lets you run 'make oldconfig' and 'make menuconfig' on systems

     2 where shared libraries aren't easy.  (There's no harm in using the

     3 static version of libkconfig.)

     4 Idea mentioned by Bertrand Marquis, but this patch is a bit simpler than his.
