The traditional 68000 processors and the newer reduced instruction set ColdFire processors do not support the 32*32->64 multiply or the 64/32->32 divide instructions. This is not a difference based on the presence of a hardware MMU or not. Create a new config symbol to mark that a CPU type doesn't support the longer multiply/divide instructions. Use this then as a basis for using the fast 64bit based divide (in div64.h) and for linking in the extra libgcc functions that may be required (mulsi3, divsi3, etc).
