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.

AROPT = crs
Support for Intel compiler on Linux

On Linux, use --enable-new-dtags when specifying -rpath to linker. This should allow LD_LIBRARY_PATH to work as desired. Per trouble report from Andy Colson.

# Use --enable-new-dtags to generate DT_RUNPATH instead of DT_RPATH.
# This allows LD_LIBRARY_PATH to still work when needed.

Use -fPIC on Sparc, per Tom Callaway.

Remove port specific Makefile 'targets' (ie. shared libraries) from Makefile.global and move them to seperate 'include' makefiles Over time, should become even more port specific: ie. Makefile.BSD44_derived should be broken down into netbsd/freebsd specific ports

Split the LDFLAGS make variable into two parts: LDFLAGS is now used for linking both executables and shared libraries, and we add on LDFLAGS_EX when linking executables or LDFLAGS_SL when linking shared libraries. This provides a significantly cleaner way of dealing with link-time switches than the former behavior. Also, make sure that the various platform-specific %.so: %.o rules incorporate LDFLAGS and LDFLAGS_SL; most of them missed that before. (I did not add these variables for the platforms that invoke $(LD) directly, however. It's not clear if we can do that safely, since for the most part we assume these variables use CC command-line syntax.) Per gripe from Aaron Swenson and subsequent investigation.
