bootloader size too big with gcc 4.4 and standard Makefile configuration

What steps will reproduce the problem?
1. run make in bootloaders/atmega644p with PROGRAM = ATmegaBOOT_644P and
MCU_TARGET = atmega644p, using gcc 4.4
2. upload the bootloader image to an Atmega 644p

What is the expected output? What do you see instead?
The bootloader should be succesfully uploaded. But it will not be
completed, because the image size is too big (2192 bytes for me).

What version of the product are you using? On what operating system?
Sanguino-0018r1_1_4.zip
running on Gentoo Linux

Please provide any additional information below.
The problem can be solved by switching from -O2 to -Os in the Makefile
(size is then 2006 bytes)
