Move DLSUFFIX, AROPT, and CFLAGS_SL settings from template to

Makefile.port, since they are of no use to configure and much of the
library magic happens in Makefile.port anyway.

Use __alpha, not __alpha__, since the former is universally available.
Remove -DNOFIXADE from the compile command line and put it in the port
include file.
