Avoid tickling a linker bug from microblaze pt-vfork.S.
libpthread used to have its own vfork implementation that differed from libc's only in having a pointless micro-optimization. There is no longer any use to having a separate copy in libpthread, but the historical ABI requires a compatibility shim. microblaze was trying to be slightly too clever about how it did this, and tickled a linker bug. The linker bug should get fixed eventually, but there's no reason for us to keep tickling it in the meantime. This doesn't reuse the generic pt-vfork.c because microblaze doesn't have IFUNC support yet, and it doesn't reuse aarch64/pt-vfork.c because that fails to generate a tailcall (with GCC 7.1.1). * sysdeps/unix/sysv/linux/microblaze/pt-vfork.S: Don't include alpha/pt-vfork.S. Provide own compat shim for vfork and __vfork. * sysdeps/unix/sysv/linux/microblaze/vfork.S: Add __libc_vfork alias. * sysdeps/unix/sysv/linux/microblaze/localplt.data: libpthread.so no longer references __errno_location.
