The same error also occurs on sparc64-linux and arm-linux-gnueabi.  It's caused
by r180302:
http://gcc.gnu.org/ml/gcc-cvs/2011-10/msg00898.html

find_all_hard_reg_sets does have a prototype in rtl.h, but it's conditional on
#ifdef HARD_CONST.  Deleting the #ifdef causes build errors, but changing the
include order in rtlanal.c so that hard-reg-set.h is included before rtl.h
solves the bootstrap problem.
