I've attached a patch to include -static-* and -fcilkplus options.
I assume that by default, any -static-* option should be passed to
the linker. Thus -static-* would take into account new future options.
Exceptions to this rule should be handled earlier in the "case"
construct, as already done for -static-libtool-libs.
