Thanks for the bug erport.

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?  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.

Please also post
  cc -V
  CC -V
  f90 -V

for this version of the compiler, so we can try to differentiate from
the older versions.

Thanks,
Ralf
