Re: [PATCH 0/1] Cross-compiling 32-bit macOS from 64-bit-only macOS.

[Dean Greer]

I might have a cleaner solution for you.

Copy the following;
Xcode9.4.1.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain

Rename XcodeDefault.xctoolchain > Xcode9.xctoolchain

Open ToolchainsInfo.plist
Remove the current contents and add the following;
CompatibilityVersion        Number        2
DisplayName                   String            Xcode 9.4.1
Bundle identifier               String            Xcode9.toolchain

Now move to ~/Library/Developer/Toolchains/

The toolchain is now visible within Xcode, it can also be used by setting;
export TOOLCHAINS="Xcode9.toolchain"

Just need to set SDKROOT as appropriate.
