crosstool-ng: CREDITS@ea15433daba0

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 I would like to thank these fine people for making crosstool-NG possible:

     3   Dan KEGEL, the original author of crosstool: http://www.kegel.com/

     4     Dan was very helpfull and willing to help when I build my first toolchains.

     5     I owe him one. Thank you Dan!

     6     Some crosstool-NG scripts have code snippets coming almost as-is from the

     7     original work by Dan.

     9   Allan CLARK for his investigations on building toolchains on MacOS-X.

    10     Allan made extensive tests of the first alpha of ct-ng on his MacOS-X

    11     and unveiled some bash-2.05 weirdness.

    13   Enrico WEIGELT for some improvements of the build procedure:

    14     - cxa_atexit disabling for C libraries not supporting it (uClibc)

    16   Robert P. J. DAY:

    17     - some small improvements to the configurator, misc prompting glitches

    18     - 'sanitised' patches for binutils-2.17

    19     - patches for glibc-2.5

    21 More to come as they help.
