I think this related to PR 14435. But reading the docs (there is a section in there which is useful to
read):
In addition, the prefix is used in an unusual way in finding the directories to search for header files. For
each of the standard directories whose name normally begins with /usr/local/lib/gcc (more precisely,
with the value of GCC_INCLUDE_DIR), GCC tries replacing that beginning with the specified prefix to
produce an alternate directory name. Thus, with -Bfoo/, GCC will search foo/bar where it would
normally search /usr/local/lib/bar. These alternate directories are searched first; the standard
directories come next.
