Yeah, it is very common. Lots of distributions patch their toolchains such that they don't compile firmware code correctly. Firmware isn't a common target, so I understand that it happens. For coreboot we recommend to build a vanilla toolchain using known good versions. We also have a script to do that. (The script is at util/crossgcc/buildgcc in the coreboot repo.) //Peter
