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
          UPD     include/generated/utsrelease.h

        make[2]: *** [scripts/mod] Error 2
        make[1]: *** [scripts] 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.
