PATCH: Fix bootstrap

PATCH: Fix bootstrap

[H.J. Lu]

Bootstrap was broken:

cc1: warnings being treated as
errors/net/gnu-13/export/gnu/src/gcc/gcc/gcc/ddg.c: In function
‘add_cross_iteration_register_deps’:
/net/gnu-13/export/gnu/src/gcc/gcc/gcc/ddg.c:242: error: unused
variable ‘bb_info’
make[5]: *** [ddg.o] Error 1
make[5]: *** Waiting for unfinished jobs....

when configured with "--enable-checking=assert" due to

http://gcc.gnu.org/ml/gcc-patches/2007-07/msg02136.html

I am checking in this patch as an obvious fix.
