When I run:
./swift/utils/build-toolchain
I'm getting an error reported a few other times. Here's the complete contents of CMakeError.log:

What's confusing is the first line which seems to want the GCC assembler:
Checking whether the ASM compiler is GNU using "--version" did not match "(GNU assembler)|(GCC)|(Free Software Foundation)"
But it seems to build the toolchain along with all the SDKs, it needs the XCode build toolchain (sudo xcode-select --switch /Applications/Xcode.app/Contents/Developer)
I'm a bit confused here. I'm literally just following exactly what I read in the README.md.
