[PATCH] mips: there is no __GNUC_MAJOR__

[Alexey Dobriyan <adobriyan@gmail.com>]

gcc major version number is in __GNUC__. As side effect fix checking with
sparse if sparse was built with gcc 4.1 and mips cross-compiler is 3.4.

sparse will inherit version 4.1, __GNUC__ won't be filtered from
"-dM -E -xc" output, sparse will pick only new major, effectively becoming
gcc version 3.1 which is unsupported.
