The directories in the make[3] and [2] messages above look like you might be building GCC in the source directory (.../src/gcc-5.1.0) which is not recommended. If that's the case, you might want to try the build again in a different directory (see https://gcc.gnu.org/wiki/FAQ#configure) If not, as Jonathan said, you will need to try to find the first error message in the log and figure out what it is that caused the failure (or post it here).
