Always prefer double dashes for GNU LD long options.

I discovered this while working on llvm/lld and realized export-dynamic
only supported --. Although upstream will eventually grow to support
both - and --, switch this in our build system, because GNU ld supports
both modes, and because there's some hope lld will become the default linker
for FreeBSD in the future.

Discussed with:		emaste, rdivacky
