You can also use elfnote -
You run it against an elf binary (and I presume object/library) to embed a comment within it.
There would be a bit of scripting involved but it should be straight forward engough.
and if you want to port it to solaris, then that would be fab...

Instead of declaring the string as static (which is convenient because
you can use the same variable name for each string), use a different
name (to keep the linker happy) and remove the static (forces compiler
to emit the string in the .o, because it can't know if it is used by
other .o files):
------ foo.c ------
const char foo_ver = "@(#) $Id";
------ bar.c ------
const char bar_ver = "@(#) $Id";
