On i686, both 'lame' and 'jemalloc' fail to compile with very similar errors when compiled with gcc-4.9.2:
http://hydra.gnu.org:3000/build/528901/log/tail-reload http://hydra.gnu.org:3000/build/531046/log/tail-reload In both cases, the errors are of the form: /gnu/store/0cp1i7q70ip8py0mks6sbbnrxzb7p7d5-gcc-4.9.2-lib/lib/gcc/i686-pc-linux-gnu/4.9.2/include/[ex]mmintrin.h: error: inlining failed in call to always_inline <builtin_func>: target specific option mismatch Mark
