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 The following fixes an error that occurs when building glibc-2.3.2 (but not glibc-2.2.5) for sh4:

    32 It seems that the definitions in asm/user.h and the above patch collide.

    33 I'm not sure why you need this patch, but is it needed for the problem

    34 about struct ustat that you pointed out in this list, isn't it?

    35 I found why I don't hit ustat problem - my local kernel tree includes

    36 the following patch, though I can't recall about it.

    37 

    38 Regards,
