PowerPC64 st_other decoding in readelf 

localentry:1 is a valid encoding, so display it.  The patch also bails
out of get_ppc64_symbol_other when st_other bits besides the three
used for localentry offsets are set, to avoid hiding any such values.

	* readelf.c (get_ppc64_symbol_other): Return NULL if st_other
	field contains unrecognised or reserved values.  Handle
	localentry:1 value.
