So it seems there is code consolidation and additionally there's seems to be a 
semantical change to ldso mmap().

Assuming __ARCH_USE_MMU__ is true for say ARC, now we have _MAP_UNINITIALIZED == 0 
vs. before MAP_UNINITIALIZED == 0x4000000.

So we won't be zero init ldso anon mmaps - which could be functionally OK, but I 
think better to split it out as a seperate patch just to call this out !
