Created attachment 516500 [details] build.log It seems that as a part of mitigating a -Werror-related FTBFS, the maintainer of the package added a pragma to ignore -Wimplicit-fallthrough. Unfortunately, since this warning was implemented in GCC 7, it is not available in GCC 6, and there, the build fails with the following error: powerpc-unknown-linux-gnu-gcc -MMD -MP -D_BSD_SOURCE
