commit 68c3b6ff97a3139b8faeb4362d309860b3f0cca3 Author: Stefan Reinauer stefan.reinauer@coreboot.org Date: Sun Apr 3 20:52:01 2016 -0700
crossgcc: Fix compilation on Clang systems
Most cross compilers fail to compile on systems with Clang being the default compiler (OS X and some BSDs). Clang dislikes some of GCC's autogenerated code. We also missed switching CFLAGS to CXXFLAGS when GCC switched to C++ compilation per default.
