Remove more copies of Tcl's SunOS shared library hack.

It's worth pointing out that the Tcl project used to
*recommend* that application writers copy this kludge.
These ports work fine with Tcl 8.3, which provided a fake
matherr() even if the OS didn't, but here's what the
Tcl 8.4 changelog has to say:

  2002-05-31 (dead code)[474335,555635] removed all use of matherr() (english)
          *** POTENTIAL INCOMPATIBILITY ***

The following lines can be safely removed from any application that
has them, unless compatibility with SunOS 4.X is desired.

  extern int matherr();
  int *tclDummyMathPtr = (int *) matherr;

The build problems were pointed out by Kris, as usual.  ;-)
