MIPS: Fix wrong CHECKFLAGS (sparse builds) with GCC 5.1
GCC 5.1 defines __REGISTER_PREFIX__ to $. This will break sparse command line (and build fails with: /bin/sh: syntax error: unexpected "(") since make tries to expand starting with the dollar sign with a make variable. Prevent that by using double dollar sign.
