Unfortunately that is fundamentally incompatible with our shared
library scheme. With .a libraries, the linker can pick and choose what
.o files it brings in. With .so libraries, it's the whole library or
nothing. You'd have to redesign shared libraries so as to avoid this
before you're likely to fix this.
