fixes for "command input -o output" when POSIXLY_CORRECT=1

[Paul Eggert]

POSIX says that command options must come before operands, and when
POSIXLY_CORRECT=1 several GNU command enforce this, but Automake generates
makefiles that do not follow this rule in some cases.  I observed this
problem with Autoconf when fixing the POSIXLY_CORRECT=1 bug reported in
<http://mail.gnu.org/pipermail/autoconf/2002-October/014258.html>.
So I installed this patch into Automake.

        * lib/am/texibuild.am (%DEST_PREFIX%%DEST_SUFFIX%,
        %DEST_PREFIX%.dvi, %DEST_PREFIX%.pdf): Use "makeinfo -o output
        input", not "makeinfo input -o output", as the latter fails if
        POSIXLY_CORRECT=1.
        * lib/am/texinfos.am (.dvi.ps): Likewise for dvips.
        * m4/depend.m4 (_AM_DEPENDENCIES): Likewise for $depcc.
