           Summary: [3.4 regression] -fprofile-arcs no longer creates

As shown in testsuite runs,

-fprofile-arcs no longer creates the *.da (though based on the testsuite, I'm
assuming that these were recently renamed to *.gcra) which are used for
-fbranch-probabilities.

This feature works fine under cygwin in 3.3.

In addition, a profiledbootstrap now fails for the exact same reason, this was
working until recently.
