I think this sounds like an extremely bad idea.  You could probably do
it by modifying the stock linker script (lib/ldscripts/i386pe.x) to put
.rdata in the .data output section instead of in .rdata.  If that
doesn't work you'd probably have to edit the source (emultempl/pe.em). 
Even then there's a good chance the read-only-ness of any section named
rdata is enforced by the operating system, so it wouldn't work just to
remove the SEC_READONLY flag, although that's pure speculation on my
part.

Again, this sounds like an absolutely awful way to accomplish whatever
it is that you're trying to do -- a hammer is not a screw driver, use
your tools as they were designed, etc.

Wouldn't it be a whole lot easier to just remove "const" from the
variable's declaration?
