[git commit] buildsys: Add MIPS64R2 support

[Bernhard Reutner-Fischer]

commit: http://git.uclibc.org/uClibc/commit/?id=79c0857a828abb3f7ec9582a01d706e0ce81f84c
branch: http://git.uclibc.org/uClibc/commit/?id=refs/heads/master

There is support for mips64(r1) already in uclibc, this change adds mips64r2
by adding the MIPS64R2 config variable and checking it in Rules.mak.
