[PATCH] Fix libgfortran on darwin, hpux and cygwin ( PR libfortran/24991)

[Jack Howarth]

Jakub,
    Below is the results for the gfortran testsuite with your proposed patch.
The undefined symbol issue is resolved. However since that is fixed, another
problem has been exposed related to the use of memmove calls in libgfortran
since you threading patch went in. Please go ahead and apply your proposed
patch so we can progress onto fixing those problems.
                      Jack
ps This build was on Darwin_8.3.0.
