Since commit f0e98c387e ("[SPARC]: Fix
link errors with gcc-4.3") the MNA trap handler does not emulate
stores to unaligned addresses correctly. MNA operation from both
kernel and user space are affected.
A typical effect of this bug is nr_frags in skbs are overwritten
during buffer copying/checksum-calculation, or maximally 6 bytes
of data in the network buffer will be overwitten with garbage.

o sparc32 files with identical names to sparc64 renamed to <name>_32.S
o introduced a few Kconfig helpers to simplify Makefile logic
o refactored Makefile to prepare for unification
- use obj-$(CONFIG_SPARC32) for sparc32 specific files
- use <name>_$(BITS) for files where sparc64 has a _64 variant
- sparc64 directly include a few files where sparc32 builds them,
refer to these files directly (no BITS)
- sneaked in -Werror as used by sparc64
o modified sparc/Makefile to use the new names for head/init_task
