Fortran libs update

[Ralf Wildenhues]

Hi there,

Autoconf and Fortran experts please have a look at the patch proposed
below, which is necessary for the Libtool testsuite to pass in
combination with the Sun Fortran 95 8.0 compiler (Solaris 10).

I'm afraid the weeding out of double arguments could kill some libraries
mentioned between the two flags, but we can still fix that when we
encounter it..  I have no idea whether other linkers' whole-archive
flags should be accepted as well.

The thread about this is here[1].  The name of the bug reporter is
Пухальский Юрий Андреевич, but since UTF-8 is not supposed to appear
in text documentation[2], I replaced it with the ASCII transcription.

Regards,
Ralf

        * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
        Merge `-z option' as well for the benefit of Solaris link flags.  Pass
        whole-archive (-zallextract, -zdefaultextract) options in the hope of
        unique libraries, for the Sun Fortran 95 8.0 compiler.  Bug reported
        against Libtool by Yury Puhalsky <address@hidden>.
