All the methods mentioned so far are essentially hacks working against
the linker, doing stuff behind its back.  Why not go with the flow?  Put
your data in its own section, and write a linker script to handle that
section in the desired way.  You can access the address by referencing
the linker script variables in your source code.  See section 3 of the
ld manual, particularly 3.5.3.  This should work on any platform that
uses ld.
