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.

Rule to install all needed libraries, not just the ones installed by install-lib,

     3
yet not install programs.

Needed because we can't use the main install target, as we can't build programs before
yann@1
     5
we have the final gcc installed; linking fails because libeh.a is not present,
yann@1
     6
and glibc insists on linking programs with that library.
