The size increase you noted seems to completely go away when adding
--gc-sections to LDFLAGS, but this option apparently brings its own
issues when the linker discards important unreferenced bits:

These problems can be fixed within linker scripts, but I think it might
be safer to use --gc-sections for diagnostic purposes only...

Unfortunately I have not been able to reproduce these errors with the
toolchain I am using (gcc 4.4.5 and binutils 2.20.1.20100303, based on
emdebian squeeze packages). Can you please point me to the toolchain
you are using?
