Added blurb for malloc() superseding.

Also define the unit when USE_MY_MALLOC is present, not just $mallocobj.

+$spackage comes with its own malloc() implementation that will supersede
+the version included in your C library.  Since proper memory allocation is 
+critical, you may choose to opt out from this specific implementation and
+rely on the (hopefully) more thoroughly tested version in the C library.
+
+If you change your mind later, you can always re-run this configuration
+script and recompile $package from scratch.
