Subject: [PATCH] go: fix checks for about I/O functions

Reference:
<http://lists.gnu.org/archive/html/bug-autoconf/2013-01/msg00000.html>

* lib/autoconf/go.m4 (_AC_LANG_IO_PROGRAM(Go), AC_LANG_INT_SAVE): Here,
correctly use 'os.OpenFile()' <http://golang.org/pkg/os/#OpenFile>
rather than 'os.Open()' <http://golang.org/pkg/os/#Open> (which has
more restricted semantics and incompatible signature).
