Because of bug 30820: the default GCC on our master branch sometimes
incorporates string literals containing store references directly into
the generated x86 code, broken up into 8-byte chunks within immediate
load instructions, which cannot be rewritten by our grafting code. This
issue was fixed on core-updates only. The fix fundamentally requires a
full rebuild, so it cannot be done on master.
