[Solaris] enable --whole-archive for shared-library build, disable --version-script for Solaris-ld 

Shared-library build on Solaris requires --whole-archive to be specified (option accepted by all available linkers).

At the same time, --version-script can not be handled by Solaris-ld, so it should be skipped.
-M is of no use here, since there is no syntax in Solaris-ld mapfiles that allows to version all global symbols,
not just the named ones (at least this is my impression from digging deep into the docs).
