Perhaps this is possible, but according to my admittedly limited
understanding of the matter, I don't think it should be.

I recommend the book _Linkers and Loaders_ by John R. Levine, the
moderator of this newsgroup.

I suggest you look at the documentation for the GNU versions of the
relevant programs, and the source code, if necessary. On the system I'm
using, there are manual pages for 'gcc', 'ld', 'as', and 'strip'.
These might be a good place to start. Using a debugger, such as GDB
(The GNU Debugger), is another good way of learning how code works on a
lower level.
