Subject: [PATCH 1/2] m32r: build fix for __stringify macro
This patch fixes the following build error of 2.6.30-rc3-git2:
AS arch/m32r/kernel/head.o
In file included from /include/linux/init.h:7,
from /arch/m32r/kernel/head.S:11:
/include/linux/stringify.h:9: error: syntax error in macro parameter list
/include/linux/stringify.h:10: error: syntax error in macro parameter list
This build error was caused at __HEAD macro in arch/m32r/kernel/head.S,
which uses __stringify() macro.
Remove -traditional option from EXTRA_AFLAGS for the m32r,
because the __stringify() macro depends on the gcc's variadic macro
extension function, due to commit:
Make __stringify support variable argument macros too

Subject: [PATCH 2/2] m32r: use __stringify() macro in assembler.h
Replace #x with __stringify(x).
Also, #ifndef __STR is removed and undefine __STR macro at the beginning.
The __STR() macro is still remained, because the assembler.h might be
included from assembly codes as well as C codes.
