Your most immediate problem is that you're running
gcc-4.8.1/gcc/configure when you should be running gcc-4.8.1/configure.
^^^
The configure script inside the gcc subdirectory ONLY configures the
compiler itself, it doesn't know about all the other extra stuff.
That's why it doesn't recognize those extra configure flags.
Ok.. configure went smooth.. now I have an error during make:
