It appears a solution like that is already implemented in GNU gettext
and libiconv. See the following proposal for relocatable packages,
written by the current gettext maintainer, Bruno Haible:

http://lists.gnu.org/archive/html/bug-gnulib/2003-03/msg00020.html

The mechanism does appears to be a bit elaborated. New files, new
autoconf macros, but the original source code itself would be nearly
untouched.

I intend to take a closer look in gettext sources. If I understood
correctly, this would allow relocation in a platform-independent way.
