Add localplt.data for hppa.

This patch adds a localplt.data file for hppa so that test passes.
Architecture maintainers should feel free to clean up the sysdeps code
so that some or all of the system-specific entries

libc.so: _exit
libc.so: __sigsetjmp
libc.so: _IO_funlockfile
libc.so: sigprocmask
libc.so: __errno_location
libpthread.so: __errno_location

are no longer needed.

Tested for hppa.  Note: check-execstack and check-textrel still fail;
you may wish to look at those to get to a clean baseline there (they
are less obvious for people not familiar with the architecture).

	* sysdeps/unix/sysv/linux/hppa/localplt.data: New file.
