It is impossible for anybody to help you without knowing more 
information.  What are the patches you made?  What errors did you get 
from autoconf in libgloss?  Do you have a risc-elf toolchain built?  
What options did you specify to configure newlib?  Are you using the CVS 
repository or a newlib snapshot?

For information regarding how to regenerate configuration files, see the 
README file in newlib.
