As I understand it, no -- musl targets the permanent kernel syscall
API/ABI for the arch. So if the legacy stat syscall is not going to be
part of the interface that's approved upstream in the kernel for this
arch, musl can't be using it.

Am I correct in understanding that the syscall & struct stat that are
"there now" are part of a proposed port that's not yet upstream, and
that upstream maintainers are asking for them to be removed as part of
accepting the port?
