Only relatively recent versions of SunOS.  Definitely not before
release 4.*, and possibly not before 4.1* (not sure about 4.0.3).

You simply use ld to load a bunch of .o files together.  You probably
want to use -assert pure-text.  Apparently, the most critical thing is
the .so or .so.<major>.<minor> on the resulting file.

(You want to compile with -pic, and build the .so file with -assert
pure-text, because otherwise all the fixups that have to go on destroy
many of the advantages of shared "libraries".)
