commit f627ca82fb6c469c8cf34f04f02fe2ea006304bd
Author: Chris Metcalf <cmetcalf@ezchip.com>
Date:   Thu Dec 11 15:13:48 2014 -0500

    tile: add inhibit_loop_to_libcall to string functions
    
    Without this, on gcc 4.8.2 the built glibc crashes when memcpy
    or memset are invoked, since they call themselves recursively.
    See commit 85c2e6110c9a01ec for the generic inhibit_loop_to_libcall.
