I wonder if a more generic mechanism should be put in place.

For example, I propose having a noinclude list which would contain a 
list of header files that were not to be installed and these could be 
removed at the end of header file processing in top-level newlib 
Makefile.am.

This would make such changes as this much easier to perform in the 
future by simply changing configure.host rather than having to make 
further configuration changes in libc, etc..

I have included a proposed patch that adds rpc/types.h and rpc/xdr.h to 
the list if xdr_dir is not set.  If you don't object to it, please try 
it out and let me know if I have missed anything.
