[compiler-rt] compiler-rt: Fix stat size check on mips64 musl (PR #143301)

[Jens Reidel via llvm-commits]

https://github.com/Gelbpunkt created https://github.com/llvm/llvm-project/pull/143301

The sizes of the struct stat on MIPS64 differ in musl vs glibc.

See https://godbolt.org/z/qf9bcq8Y8 for the proof. Prior to this change, compilation for MIPS64 musl would fail.
