Just try it and see.  The "_OPT" in the symbol version is internally
generated from "-opt" in the shlib_variant SONAME.  To support multiple
shlib_variants now or in the future, add the major.minor (ABI version)
to the variant tag:

	shlib_variant => "-opt1.1"
	shlib_variant => "-opt1.2"
	shlib_variant => "-somevendor-3.0"
	...

The non-alnum characters in the shlib_variant map to "_" in
the symbol version, and the letters are mapped to upper case
(IIRC).
