- 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.
