fix to buil tcl-8.5.8 on vax (and probably on m88k too)

[Sebastian Reitenbach]

Hi,

trying to compile tcl-8.5.8 failed on vax, first in compilation state,
which is fixed by the updated patch-generic_tclStrToD_c
(fis is submitted to upstream where it is already applied)

afterwards linking failed with undefined refererence to __DYNAMIC.
The update of the port Makefile fixes this linking problem.

I also added this for the m88k architecture, I guess it would suffer
from the same problem, but I am unable to test it since  I don't have
such hardware.

comments, OK?

cheers,
Sebastian
