Issue Description:

I'm trying to build SwiftSyntax for iOS using the simple steps described in the README: https://github.com/apple/swift-syntax/blob/main/README.md

git clone https://github.com/apple/swift.git
./swift/utils/update-checkout --clone
./swift/utils/build-parser-lib --release --no-assertions --build-dir /tmp/parser-lib-build-ios --host iphoneos --architectures arm64

Unfortunately that fails pretty quickly in the CC detection:

-- Check for working C compiler: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/cc
-- Check for working C compiler: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/cc - broken
CMake Error at /usr/local/Cellar/cmake/3.20.3/share/cmake/Modules/CMakeTestCCompiler.cmake:66 (message):
  The C compiler

    "/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/cc"

  is not able to compile a simple test program.

  It fails with the following output:

    Change Dir: /tmp/parser-lib-build-ios/arm64/obj/CMakeFiles/CMakeTmp

Tried the cross build for myself on an x86_64 host with Xcode 13 and ran into what I believe is a related issue.

apple/swift#38352

Could you give this fix a shot locally with Xcode 13 and see if that changes anything here? I suspect there may be a deeper issue with the M1-hosted cross build considering the -arch here is completely bogus.
