[opus] [PATCH] opusfile configury fixes.

[Ozkan Sezer]

[this time compeled the mail].

The autogen.sh of opusfile doesn't work for me:

Updating build configuration files for opusfile, please wait....
configure.ac:8: installing `./install-sh'
configure.ac:8: installing `./missing'
Makefile.am:10: Libtool library used but `LIBTOOL' is undefined
Makefile.am:10:   The usual way to define `LIBTOOL' is to add `AC_PROG_LIBTOOL'
Makefile.am:10:   to `configure.ac' and run `aclocal' and `autoconf' again.
Makefile.am:10:   If `AC_PROG_LIBTOOL' is in `configure.ac', make sure
Makefile.am:10:   its definition is in aclocal's search path.
Makefile.am: installing `./depcomp'
autoreconf: automake failed with exit status: 1

So I made configure.ac of opusfile to look a little bit more like that
of opus as seen in the first two hunks of the patch inlined below. The
last hunk touching the AC_CHECK_HEADER use is needed for me, otherwise
the generated configure is broken (using autoconf-2.63, newer versions
are _possibly_ OK with the existing syntax).

Patch is below.
