commit 116ae4fe5a70d99cf06088f0222a5913996f7f70

    Add localplt.data for sh.
    
    This patch adds a localplt.data file for sh so that test passes.  The
    architecture-specific entries are for _Unwind_Find_FDE, _exit and
    __errno_location.
    
    Tested for sh3 and sh4.
    
    	* sysdeps/unix/sysv/linux/sh/localplt.data: New file.

commit 2d5a67dc89ec0e6c1799f0bf3e7eeef817ba3b16
Author: Joseph Myers <joseph@codesourcery.com>

    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.

    Update alpha localplt.data.
    
    This patch updates alpha localplt.data so the localplt test passes in
    my compile-only all-ABIs glibc testing.  The failures I see without
    this patch are:
    
    Missing required PLT reference: ld.so: __tls_get_addr
    Missing required PLT reference: ld.so: free
    
    Now, __tls_get_addr can be made optional.  For free, rather than
    making it optional as in libc.so it seems better to mark all the
    malloc-related symbols in both libc.so and ld.so as allowing an
    R_ALPHA_GLOB_DAT relocation as an alternative to using a PLT entry, so
    this patch does so.
    
    Tested for alpha.
    
    	* sysdeps/unix/sysv/linux/alpha/localplt.data: Make __tls_get_addr
    	optional in ld.so.  Allow R_ALPHA_GLOB_DAT relocation for malloc,
    	calloc, realloc, free, memalign and __libc_memalign rather than
    	making them optional.
