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. 
     1 There are at least three weird glitches in the Makefile:

     2  - the test operator is a dual-equal sign (==) when it should be a single one (=);

     3  - the exclude options are not accepted as is by GNU tar;

     4  - how on earth could KERNEL_SOURCE possibly be equal to DEVEL_PREFIX ???

     5 

     6 We (Cedric DUVAL and I, Yann E. MORIN) are not quite sure why it is that way.

     7 We're not quite sure either on how to solve this.

     8 

     9 What we need is to built a toolchain; in no way we need to install the linux headers.

    10   ==> systematically exclude them from the [s]tar command.

    12 This patch is inspired by the svn repository of uClibc as of 20060209.
