[parisc-linux] ELF tool chain builds hello world!!!

[Paul Bame]

This recipe is a little better.  Remember it assumes /opt/puffin
contains the current cross compiler and /opt/puffin/include contains
the include.tar.gz tarball.

# Now you should be able to compile hello world

# The problem is that not all the headers seem to be available, in
# two categories: 1) some headers for example glibc/string/memory.h
# which ought to be installed as ...../include/string/memory.h, aren't
# and 2) things in <sys> like <sys/mount.h>
