Comment (by awson):

 I looks current binutils' linker scripts doesn't handle `rodata` sections
 at all, thus I believe we should patch binutils anyway.

 Regarding section namespace separator, indeed `gcc` on Windows generates
 `$` instead of `.`, and this, perhaps, would be correct to make GHC do the
 same thing, but even unpatched Windows bintuils have separate handling of
 `.text.*` sections for example. I suspect that this is because there exist
 another tools from GNU/Unix land, ported to Windows which also use `.` for
 section hierarchy handling.
