I saw the errors too, and wrote them off incorrectly as gcc errors. When we have a weakly defined symbol in an IR bfd, it isn't overridden by a weakly defined symbol in the real bfd, as per the usual behaviour of weak symbols. I'm testing a patch to plugin_notice that overcomes this problem (and does away with plugin_multiple and plugin_multiple_common).
I added a testcase on hjl/lto-test branch at http://git.kernel.org/?p=devel/binutils/hjl/x86.git;a=summary With GCC 4.6, I got FAIL: PR ld/12696 FAIL: ld-plugin/lto-4r-a FAIL: ld-plugin/lto-4r-b FAIL: ld-plugin/lto-4r-c FAIL: ld-plugin/lto-4r-d FAIL: LTO 4a FAIL: LTO 4c FAIL: LTO 4d FAIL: LTO 10 The other failures are fixed by http://sourceware.org/ml/binutils/2011-04/msg00295.html
