Ahh, so Solaris Studio changed their Fortran compiler characteristics.
libtool.m4 has:

        case `$CC -V 2>&1 | sed 5q` in
        *Sun\ F* | *Sun*Fortran*)
          # Sun Fortran 8.3 passes all unrecognized flags to the linker
          _LT_TAGVAR(lt_prog_compiler_pic, $1)='-KPIC'
          _LT_TAGVAR(lt_prog_compiler_static, $1)='-Bstatic'
          _LT_TAGVAR(lt_prog_compiler_wl, $1)=''
          ;;
        *Sun\ C*)
          # Sun C 5.9
          _LT_TAGVAR(lt_prog_compiler_pic, $1)='-KPIC'
          _LT_TAGVAR(lt_prog_compiler_static, $1)='-Bstatic'
          _LT_TAGVAR(lt_prog_compiler_wl, $1)='-Wl,'
          ;;

which looks like old Fortran compilers didn't accept a -Wl, or '-Qoption
ld' argument to pass flags on to the linker.  Or maybe it still doesn't,
but -r is detected as a compiler argument now.  See also
http://lists.gnu.org/archive/html/libtool-patches/2006-05/msg00011.html

Can you confirm whether -Wl, or '-Qoption ld' is accepted by Solaris
Studio 12.2 f90 for GNU/Linux now?

Either one seem to work with Studio 12.2 and both show up in the
-flags output.
I checked an earlier Studio circa 2009 and only -Qoption works and
only shows up in -flags output.

 The online docs don't seem to
present me with different man pages for the Solaris and the GNU/Linux
versions, but I am fairly certain that the old versions did not accept
the flags.

Thanks.  Now the only remaining question is whether we still need to
support that thing called 'Sun Ceres Fortran' here:
http://www.open-mpi.org/community/lists/devel/2008/11/4932.php
and if yes, whether that also supported '-Qoption ld' already, despite
a hint to the contrary in that reference.

Any chance one of you might know/remember this?

Like a bad recurring nightmare :-).

Note the f90 2009 compiler is the 8.4 where Ceres was 8.3.  So from 8.4 on -Qoption is supported.  I think we probably would want to still support Ceres but let me ask around.
