The latter seems to kind of delay them, so part of actual assembler code is now before the first emitted split marker, which then is erroneously taken as prologue material and copied into every split assembler source resulting in lots of duplicate definitions. As a temporary workaround, a build with --with-gcc=gcc-4.1 succeeds.
