bug in fortran.m4 _AC_FC_LIBRARY_LDFLAGS

I think that I've found a bug in this function,  I am using pgf90 10.3-0
and the -v flag is producing a line which includes a flag -list which is
interpreted as a library and causes a failure later when it trys to link.

In the function I found:

      # Ignore these flags.
    -lang* | -lcrt*.o | -lc | -lgcc* | -lSystem | -libmil | -little \
      |-LANG:=* | -LIST:* | -LNO:* | -link )

And the obvious thing to do is add -list to this list.   I did that and it
solves the problem.   But this list seems really kludgey to me - wouldn't it
be better to test link with all of the -lwhatever
flags and keep the ones that pass that test?
