**Please** don't go this route: it makes feature tests completely
unmaintainable. Consider the Solaris case where initially only `/bin/ld` was
supported which didn't accept `-Bsymbolic-functions`. Only later when GNU `ld`
became an alternative linker that one **would** support that option. How on
earth is one supposed to know that I now have to revise the cmake check to
detect this if it were restricted to some platforms?
