    powerpc-lynxos and powerpc-windiss fixes
    
    Enabling shared lib tests showed the powerpc-lynxos target is broken,
    and has been for a long time.  The breakage happened in a 2005-05-07
    patch of mine, git commit 3b36f7e62, I think.  There have been no bug
    reports I recall so it seems the target is dead.  powerpc-windiss is
    similarly broken.
    
    This patch fixes the breakage, and puts the targets on the obsolete
    list.
    
    bfd/
    	* config.bfd: Add powerpc-*-lynxos* and powerpc-*-windiss*
    	to obsolete list.
    ld/
    	* emulparams/elf32ppcwindiss.sh: Rewrite to use elf32ppc.sh.
    	* emulparams/ppclynx.sh: Likewise.
