[binutils-gdb] Fix detection of "r_fs" and "r_gs" on FreeBSD.


https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;h=a6e69c1f1de84549d99792031dd05d5ba70bd8a5

commit a6e69c1f1de84549d99792031dd05d5ba70bd8a5
Author: John Baldwin <jhb@FreeBSD.org>
Date:   Mon Jan 18 11:59:45 2016 -0800

    Fix detection of "r_fs" and "r_gs" on FreeBSD.
    
    Include <sys/types.h> as a prerequisite for <machine/reg.h> when checking
    for the r_fs and r_gs members in struct reg.  Note that the previous test
    for <machine/reg.h> already includes <sys/types.h> as a prerequisite.
    
    gdb/ChangeLog:
    
    	* configure.ac: Include <sys/types.h when checking for "r_fs" in
    	"struct reg".
    	* configure: Regenerate.
