Work around ksh93 bug that broke config.status
* lib/autoconf/status.m4 (_AC_OUTPUT_HEADER):
Use ‘>&1’, which is a no-op, to work around a bug in ksh93
Version JM 93t+ 2010-03-05 as used in OpenIndiana.
The bug causes ‘printf "foo"’ to mistakenly succeed in
some cases even though the underlying ‘write’ syscall fails.
The ‘>&1’ causes the printf to fail, as it should.
