Linaro toolchain bug: https://bugs.linaro.org/show_bug.cgi?id=2123 Patch to fix it https://gcc.gnu.org/ml/gcc-patches/2016-03/msg00522.html It is supposed to be included in the linaro 5.3-2016.03 snapshot. I've pinged Christophe to see if I can get any insight into when that will be available. It is kind of nice to see that when it fails, it prints a helpful message, though: scripts/Makefile.gcc-plugins:22: *** error, your gcc installation does not support plugins, perhaps the necessary headers are missing?. Stop. I think it is OK to include this, even with the patches still bubbling through gcc releases. It prints a helpful message when it doesn't work, and is only going to be selected if specifically requested. David
