[Removed uclinux-dev from the CC line cause that's a subscriber-only list and I can't be bothered with subscribing to each and every list on this planet. Cross posting between a closed list and other lists is considered rude, http://www.arm.linux.org.uk/armlinux/mletiquette.php#e10 ]

How to use it to descrease the size of library?
Compile with -Os and without -g.
Ya, compiled with -Os only but still want to reduce the size of the kernel image.
The kernel is not a shared library nor does it use a shared library, so library Optimizer is useless on the kernel.
You should enable EMBEDDED (General setup --> Configure standard kernel features), remove all unneccessary stuff. "find . -name Kconfig | xargs grep EMBEDDED" will tell you more about options that depend on EMBEDDED. Another good one to remove is the many IO schedulers (Device drivers --> Block Devices --> IO Schedulers).
You might want to look at the linux-tiny project -

I haven't played with it too much, but its on my list of "Things to use to get my old 386 running Linux."
