The stat structure on linux/mips64x differ between C library and the kernel,
as described in the stat(2) man page.

Fstat, Lstat and Stat on linux/mips64x already converts the stat structure
using a fillStat_t function, very similar to __xstat_conv in GLIBC.
Doing the same for Fstatat before calling SYS_NEWFSTATAT fixes the
"Fstatat: returned stat does not match Stat/Lstat" error in TestFstatat.

Raw syscalls are not a supported ABI on Darwin, they want us to use

The stdlib has already been converted to this new regime.  This
package is vendored into the stdlib, so we need to fix it also, then
vendor it in again.

Because this package isn't tied to a Go release, we need to keep the
