sparc32: fix build with STRICT_MM_TYPECHECKS
Based on recent thread on linux-arch (some weeks ago) I decided to check how much work was required to build sparc32 with STRICT_MM_TYPECHECKS enabled. The resulting binary (checked srmmu.o) was to my suprise smaller with STRICT_MM_TYPECHECKS defined, than without. As I have no working gear to test sparc32 bits at for the moment, I did not enable STRICT_MM_TYPECHECKS - but was tempeted to do so.
