Target Milestone: ---
Building for mips64-unknown-linux-gnu with libsanitizer enabled the following
static_assert is triggered.

Looking at the libsanitizer code I see
#elif defined(__mips__)
const unsigned struct_kernel_stat_sz = SANITIZER_ANDROID
? FIRST_32_SECOND_64(104, 128)
: FIRST_32_SECOND_64(144, 216);
const unsigned struct_kernel_stat64_sz = 104;
But from the Linux kernel's arch/mips/include/uapi/asm/stat.h I make the size
of struct stat 104 for the _MIPS_SIM_ABI64 case. The 144 seems to line up with
the _MIPS_SIM_NABI32/_MIPS_SIM_ABI32 case.
Where did libsanitizer get 216 from?
