The 'mips' type targets are big-endian, 'mipsel' type targets 
little-endian, so when you define the host/target being 
'mips-unknown-linux-gnu'
and don't the configure script to check what the system is, you got just 
what you seemed to want!  So if you had left this away and had
configured with :

    ../gcc-4.8.2/configure --prefix=/usr/local --disable-nls --enable-languages=c,c++

you probably had succeeded...

Ok, you can check what the configury system would tell your system being 
via running :

     ./config.guess

in the main gcc-4.8.2 source directory.
