is $RTEMS_DEV/rtems/4.12/bin in your $PATH?

I have no clue where you are in your directory tree. It is a bit
confusing/deep paths.

You should use --enable-posix probably.

The --disable-itron is obsolete / does nothing.

Check that your configure ended with something stating it was ready to
make 'riscv_generic' BSP.

This is not enough of the error output to tell what went wrong. It
appears to be a problem earlier though, likely during configure.
