AFAIK, multiple -B flags accumulate, and they're searched
left-to-right.  Therefore, the change is actually arranging for
installed binaries to be preferred over non-installed ones, which is
obviously wrong.  BTW, wouldn't it cause the installed `cpp' driver to
be found when what we want is the actual preprocessor, in the gcc
build directory?

This is really strange.  There must be something wrong with -B
handling, then.
