bsd.linker.mk: Use :C not :S for regex

Browse Source 
Whilst ^ and $ are supported with C, those are special cases, and
general regex syntax like groups and alternations are not. Use the
correct modifier so we get a version number out that's not 0 (which is
what happens when it can't be parsed by the later code).
