When trying to compile the 3.1-rc10 kernel for my MIPS board with C=1
(sparse checking), the build fails early with the error:

	  CHK     include/linux/version.h
	  UPD     include/linux/version.h
	  CHK     include/generated/utsrelease.h

	make[3]: *** [scripts/mod/empty.o] Error 2
	make[2]: *** [scripts/mod] Error 2

It seems the shell chokes because sparse is called with command line
arguments such as:

	-D__INT8_C(c)='c'

Converting these to form:

	-D'__INT8_C(c)'='c'

seems to fix the problem.
