Which version of the linker are you using? Can you try a newer version?
I used GNU Binutils 2.21.1 (the latest release). I installed now
2.21.53.20110922 (2.22 release branch). This didn't work. Then I checked the
Binutils configure options and added "--enable-lto".
/home/sh/archive/binutils-2.21.53/configure --target=arm-rtemseabi4.11
--prefix=/opt/rtems-4.11 --disable-nls --disable-win32-registry
--disable-werror --enable-lto
With this I still get:

If I add "-Wl,--allow-multiple-definition" as suggested by Xunxun the link
process succeeds.
