New Revision: 278306
URL: https://svnweb.freebsd.org/changeset/base/278306
Log:
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.
