gzip-compressed build log of gcc-5 (r225710) on sh4

Hello!

After checking with the gcc-5 build logs for the other architectures in Debian
which do not exhibit this particular comparison failure, I have decided to file
this as a bug against upstream. This particular comparison failure also doesn't
show with gcc-4.9, albeit I don't know whether gcc/real.o exist on gcc-4.9.

Here is the tail of the build log:
