You should add "--soname libico.so.1" to the ld command line. You
also needs the "--whole-archive" switch to force loading of the entire
archive file if you create the shared library out of an libico.a archive.
And the "-shared" switch of course.

You can also have a look in "/usr/share/mk/bsd.lib.mk" for the exact command
to make a share library from an .a file. (check 'mips' ifdefs!)

Good luck!
