Created attachment 54788
  --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=54788&action=edit
Patch which improves the depedencies

Note I am not 100% sure this is all the way. But you should get the idea and
take it over from there.

I can reproduce the problem with crosstool-ng, and it has resolved by Andrew
Pinski's fix, I am reviewing the dependency in the file.

Plan to drop a complete version of patch later :)
