Yann E. MORIN" 721da92158 Move the whole threading ;odel choice out of glibc and into the generic C library options: even uClibc may have NPTL at one point in the (hopefully near) future.
Mark the progress bar as being CPU-intensive.
Little style fix to the core C compiler build step.

# Ah! gcc folks are kind of 'different': they store the tarballs in
# subdirectories of the same name! That's because gcc is such /crap/ that
# it is such /big/ that it needs being splitted for distribution! Sad. :-(
# Arrgghh! Some of those versions does not follow this convention:
# gcc-3.3.3 lives in releases/gcc-3.3.3, while gcc-2.95.* isn't in a
# subdirectory! You bastard!
