stack_t is sigaltstack, which in musl has a special definition for MIPS that switches around ss_size and ss_flags. The 32-bit definition was already correct. See: https://git.musl-libc.org/cgit/musl/tree/arch/mips64/bits/signal.h#n67 Signed-off-by: Jens Reidel <[email protected]>

…labi64-target-maintainer, r=jieyouxu Add target maintainer information for mips64-unknown-linux-muslabi64 The `mips64-unknown-linux-muslabi64` target is currently rather broken, but I'm working on getting it fixed so that it can at least be used again. While I can't commit to maintaining the LLVM side of this target, I don't mind looking into any other MIPS or musl-related issues that arise with this target. See e.g. rust-lang#143409 for some rustc fixes I have in the pipeline and rust-lang/libc#4509, rust-lang/libc#4527, rust-lang/libc#4528, rust-lang/libc#4529, rust-lang/libc#4530 for fixing the libc definitions for this target. I'm adding myself as a maintainer mostly due to [this interaction](rust-lang/libc#4530 (comment)). LLVM support has been a concern for these targets in the past, but it shouldn't hurt to have a nominal maintainer for these even if they remain tier 3. From my experience, LLVM for MIPS is working well nowadays unless you decide to use LLD, which is horribly broken on MIPS.

The 32-bit definition was already correct.
