openjdk8: mips* support
Builds for all mips* platforms, using the zero backend. A mips port
properly is in process but has been "getting close to ready" for years
now, so we are using the much more tested zero backend.

mipshf had a branch jump error (mips hates super large branch jumps).
This is a known bug that is not going to be fixed very easily. To
workaround this, I reduced the jump by ~400 lines of assembly by
compiling with -Os, enough to make the jump close enough.

The mips support patch was taken from debian, I left mips64 in there because it might be useful in the future, we don't lose anything by having it there. (I debated putting the whole patch with all the extra archs in there, but it looked a bit unwieldy then)
