Issue Description:

When you clone a fork of the Swift repository (hence, origin now points to the fork), run update-checkout and try to build the project, you get some strange failures as part of building the sanitizers. See also: https://forums.swift.org/t/problems-with-building-the-swift-compiler/39833

I also encounter this problem too.

More info, hope it help you.

macOS Catalina 10.15.7

xcode Version 12.2 beta 3 (12B5035g)

build for swift-5.2.4-release not swift-5.3-release

• repo version hash code:

     def self.swift
        return "0bab712aea8f0eb74f3acc303d96857f697a98d8"
  
     def self.llvm
        return "c2133f2b08047708b17230b598cb789062143650"
  

• error log:

Possibly unrelated: The commit hash for LLVM looks incorrect. swift-5.2.4-release corresponds to c4513204aeb003122d2c69bd454ab8781298453b, not c2133f2b08047708b17230b598cb789062143650 (this one corresponds to swift-5.2.3-release and earlier).

(Also: JIRA has its own markup which is distinct from Markdown.)

[typesanitizer]

Can you try reproducing with utils/update-checkout --tag swift-5.2.4-release (I think that should work...)? Also, it says dev_kit on a path, is the error on an Apple Silicon Mac or an Intel Mac?

Sorry for my clerical error:

• llvm for swift-5.2.4-release : c4513204aeb003122d2c69bd454ab8781298453b

not working, thanks your reply.

And it's really working on `xcode 11 with macOS 10.14.x` before update my macOS to 10.15.x .
