fix broken Xtensa property tables

Xtensa object files include "property tables" to provide extra information about 
the contents of other sections.  This patch disables the creation of property 
tables for merged string sections.  The problem is that if a string (or other 
data object) is merged, any property table entry associated with that object is 
left hanging around, and this can lead to invalid property tables.  It's 
unlikely that property tables will be needed for merged sections, anyway, since 
they are primarily used for link-time relaxation of sections containing code.

Tested with an xtensa-elf target, and committed on the mainline and 2.16 branch.

	* config/tc-xtensa.c (xtensa_create_xproperty_segments): Skip
	SEC_MERGE sections.
