games/fs2open: fix linking on 12.0 and higher when using LLVM

[pkubaj]

Summary

This port was tested on 11.2-RELEASE (the oldest supported version) on amd64 and 12.0-RELEASE on powerpc64. Since 12.0-RELEASE amd64 uses lld.

This port doesn't link with lld. Fix that (LLD_UNSAFE doesn't work) and remove additional -march=native.

[mat]

Though, the last two patches should be excluded, nothing in them changes really.

FreeBSD 13.0 does not have ld.bfd in base anymore, so committing this would break the build there. Either add something like

.if !exists(/usr/bin/ld.bfd)
USE_BINUTILS=	yes
.endif

or make sure the build respects LDFLAGS so that LLD_UNSAFE=yes can actually work.

[pkubaj]

That seems to build.

OK?

[tobik]

Looks good to me and builds fine on 13.0/amd64, thanks.

I'd bump PORTREVISION too to trigger a rebuild since the build is without -march=native now and because CFLAGS, CXXFLAGS, LDFLAGS are actually respected by the build now.

[pkubaj]

Bump PORTREVISION.

Remove this patch from the lot, no functional changes. (I am looking at fixing makepatch to avoid keeping those patches.)

Fixed in rP502102.

Remove patch that doesn't change anything.
