OpenJDK fails to build on mips and mips64el after JDK-8304913

[Vladimir Petko]

Dear Maintainers,

After JDK-8304913, OpenJDK fails to build on mips[1] and mips64el[2].
Would it be possible to consider adding those architectures to the
Architecture enumeration (see attached patch)/

Best Regards,
 Vladimir.
