Last week I posted a patches for 3.2.3/binutils that fixes that
wastage by fixing support for -fdata-sections and -gc-sections.
One of the effects of that is that static variables are sorted
by size so that a minimal amount of RAM is wasted by alignment
fill.
The --sort-common option is supposed to do the same thing, but
it never worked for me.
