Author: Nick Clifton <nickc@redhat.com>

    Reduce the size of s390 symbol tables by allowing relocations in mergeable string sections (eg .debug_str) to be made section relative rather than symbol relative.
    
    	PR gas/21333
    	* config/tc-s390.c (tc_s390_fix_adjustable): Allow non pc-relative
    	fixups in mergeable sections to be adjusted.
