The obsolete mips header rides again! The most interesting part of this change is that I've removed the hack that meant that all system call wrappers starting with `__` defaulted to being hidden symbols. That's no longer useful given our linker scripts, and it actively got in the way here because the public libc symbol actually starts with `__` in glibc, and it would be weird and annoying for developers if we chose a different name.
