__attribute__((weak)) doesn't work on all the platforms we need
to support, I'm afraid. The approach we've settled on instead
is to provide stub functions in source files in the stubs/ directory
which get built into a libqemustub.a library; then the linker will
fish out the .o files from that as needed to satisfy otherwise
missing symbols.
