I have done that all the time. I just combine a known good gcc source tree
with a known good binutils source tree. The main problem is many times
the common directories, like include, libiberty and top level files, aren't
compatible between gcc and binutils. My solutions are

1. Use PATH for build/testing if I can't use combined tree.  Or
2. Patch the common directories/files so that they are compatible between
gcc and binutils.

I thought it was my problem. I believe such changes belong to vendor
branches, not gcc trunk.
