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.

by fixing slightly incorrect code in glibc (the .eh_frame section used to

so it's arguably incorrect to continue to put variables in there that aren't const).
