Comment (by kencu):

 It looks like you're trying to build against one of the iphone SDKs...that
 is not likely going to work out. llvm-9.0 will try to build libclangrt.a
 against all the archs that are supported on a given system, so presumably
 that is where this mess is coming from.

 this is going to take some work. I admire your pluck, but -- building rust
 on a new OS version is not for the timid...

 You most likely want librsvg? If so, there is a way to build the c++
 version of that rather than the rust version, and that would be much
 easier at this juncture. Just edit the librsvg Portfile and force it to
 the c++ version -- you'll see where easily enough.

 If nothing I'm saying makes any sense, then you're a little too far out on
 a limb, and you'll have to wait for MacPorts to catch up with BigSur and
 ARM and all the coming hoo-hah.
