commit d5bfa34a53fe67e9e86edc7f5d8277dcd687d064
Author: John David Anglin <danglin@gcc.gnu.org>
Date:   Tue Nov 28 20:01:05 2017 -0500

    Fix gmon static test failures.
    
    	* sysdeps/hppa/start.S (_start): Check PIC instead of SHARED.  Load
    	address of $global$ into %dp register earlier.  Use pc-relative
    	instruction sequence for PIC case.
