-XCOMM Construct shared-library scoping mapfile for Solaris based on standardized

-XCOMM
-XCOMM Usage: exportlistgen libfoo.so libfoo.elist > mapfile.scope
-XCOMM
-XCOMM libfoo.so => shared library of interest
-XCOMM libfoo.elist => Meta description of necessary export list.
-XCOMM
-XCOMM The output file, "mapfile.scope" may then be passed to the Solaris
-XCOMM linker to reconstruct the shared library, libfoo.so.
