On the whole it looks like we should recommend installing the CLT
and not bothering with Xcode, which is about 10X the size:

15G /Applications/Xcode.app
Fair.
BTW, Homebrew prefers the CLT SDK:
https://github.com/Homebrew/brew/blob/master/Library/Homebrew/os/mac.rb#L138
# Prefer CLT SDK when both Xcode and the CLT are installed.

# 1. On Xcode-only systems, return the Xcode SDK.
# 2. On Xcode-and-CLT systems where headers are provided by the
system, return nil.
# 3. On CLT-only systems with no CLT SDK, return nil.
# 4. On CLT-only systems with a CLT SDK, where headers are
provided by the system, return nil.
# 5. On CLT-only systems with a CLT SDK, where headers are not
provided by the system, return the CLT SDK.
Here is the relevant discussion:

I like the example of Git compiled against the wrong
LIBCURL_VERSION_NUM. Clearly, there are other issues with
cross-compiling to a newer SDK, besides autoconf probes and weak imports.
