    powerpc64le: Iterate over all object suffixes when appending -mfloat128
    
    On powerpc64le, the compilation of the files related to float128 support
    requires the option -mfloat128 to be passed to gcc.  However, not all
    possible object suffixes were covered in the Makefile.  This patch uses
    $(all-object-suffixes) in all remaining rules.
    
    Tested for powerpc64le.
    
    	* sysdeps/powerpc/powerpc64le/Makefile: Use $(all-object-suffixes)
    	to iterate over all possible object suffixes.  Add a comment
    	explaining the use of sysdep-CFLAGS instead of CFLAGS.
