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.

     7 Hi,

     8 

     9 attached you find the files I needed to add to crosstool-0.38

    10 in order to build a sh4-linux gcc-4.0.2-glibc-2.3.5 tool chain.

    14 sh4-gcc4.dat:

    15         * gcc4 needs --with-multilib-list=m4,m4-nofpu otherwise a linux

    16         kernel won't build as it uses the -m4-nofpu option.

    19         * Kaz Kojima provided a patch [really, a workaround -dank] for http://gcc.gnu.org/PR21623
