Somewhere in the libgcc build machinery, there is mechanism to override
the default LIBGCC2_UNITS_PER_WORD setting when compilng a function, so you
could in principle provide e.g. _divsi3 as well as _divdi3. It there a way
of making use of this facility in a more elegant way than putting the whole
gcc command line in a target makefile fragment?
