Hello,

-fbranch-probabilities fails to find the gcda information, because they 
are initialized only if flag_profile_use.

The problem is easily observable by recompiling with 
-fbranch-probabilities instead of -fprofile-use (after profile 
information generation)
This fails with "xxx.gcda not found, execution counts estimated".

This trivial patch fixes it. testsuite ok.

OK ?
