Here are more details:
A gcc-4.1.2 toolchain[1] produces the expected result,
the current gcc-4.4.2 toolchain[2] from 'minimal' distro does not.

I am using the very ld the toolchain provides, so I they are
different, and I noted than the 4.4.2 one gives this warning:
.../arm-oe-linux-gnueabi/bin/ld:
warning: section `.bss' type changed to PROGBITS

The problem seems to rise during linking indeed, the size difference
of .o files produced by the two toolchains is ~ 3 KiB overall, it does
not seem to justify the bump I have after linking to more than 200KiB.

I am attaching here the two binaries before stripping, but also some
scripts to easily recreate the entire scenario, since I am not sure of
what you exactly need to find out what's happening.
The command used for linking is attached as well.

Thanks,
   Antonio
