Automake 1.10 requirements for Autoconf

[Ralf Wildenhues]

I'd like to beef up Automake support for Fortran a bit, and also get
subdir-objects working better.  I'm not completely done with it, but
it would be nice if Autoconf 2.60 were prepared to deal.

So I am proposing to install the following hopefully trivial changes
now.  It is a bit conservative in the sense that I think Automake won't
need to look for AC_FC_SRCEXT or AC_FC_FREEFORM, but I don't think it
matters if the preselection is too large by a bit.  (Right?)

OK?

Cheers,
Ralf

        * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
        AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
