[libc-commits] [libc] [libc][errno] remove mips+sparc specific errnos (PR #92798)

[Nick Desaulniers via libc-commits]

https://github.com/nickdesaulniers created https://github.com/llvm/llvm-project/pull/92798

These are untested and unsupported platforms. The pattern used makes sense for
platform specific error numbers, but these are platforms we do not support.
Excise this code.
