Are you sure glibc doesn't already run on hpux?  I'd be surprised if it
didn't.

Well, you can 'stub out' with blank, no-op code the parts that you
don't want to port.

you have to do 'all of it'. But ... 
step 1 is to try to make it compile.  As you try to compile it, 
you will discover what stubs are missing, and you will have to create
those directories and files.  Start with empty/minimal files.

Once you are done compiling, you will have a minimally usable 
glibc.  It won't support thinking like dynamic library loading 
until you port the hpux ABI over ... but one thing at a time.
