Huge fixes to glibc build, so that we can build at least (and at last):
- use ports addon even when installing headers,
- use optimisation (-O) when installing headers, to avoid unnecessary warnings (thanks Robert P. J. DAY for pointing this out!),
- lowest kernel version to use is only X.Y.Z, not X.Y.Z.T,
- a bit of preparations for NPTL (RSN I hope),
- fix fixing the linker scripts (changing the backup file is kind of useless and stupid);

Shut uClibc finish step: there really is nothing to do;

Add a patch for glibc-2.3.6 weak aliases handling on some archs (ARM and ALPHA at least);

Did not catch the make errors: fixed the pattern matching in scripts/functions;

Introduce a new log level, ALL:
- send components' build messages there,
- DEBUG log level is destined only for crosstool-NG debug messages,
- migrate sub-actions to use appropriate log levels;

Update the armeb-unknown-linux-gnu sample:
- it builds!
- uses gcc-4.0.4 and glibc-2.3.6,
- updated to latest config options set.

[ Building gcc-2.95.3 on cygwin yields a compiler that sticks a .exe

  on the end of every executable, even if they're linux executable.

  This is highly annoying, and causes glibc build failures that look like this:

     4
    mv: `.../bin/makedb.new' and `.../bin/makedb' are the same file
yann@1
     5
    make[2]: *** [.../bin/makedb] Error 1

  The mainline solves this with http://gcc.gnu.org/ml/gcc-cvs/2001-04/msg00440.html,

  but that doesn't apply cleanly to gcc-2.95.3.

  This is the only patch in crosstool that *isn't* suitable for the mainline.
yann@1
    14
  I can live with this patch simply because crosstool does not build

    15
  compilers that target cygwin or VAX/VMS. 
yann@1
    16
  If that ever changes, I might need to try applying the real patch.
