There does not appear to be a way to check the Xcode / CL tools version
via a preprocessor macro, so I'm proposing the following addition to
platform/Darwin.mk to make it available as a make variable during pkgsrc
builds:

--- platform/Darwin.mk  29 Apr 2024 13:57:55 -0000      1.140
+++ platform/Darwin.mk  23 Jun 2024 12:18:31 -0000
@@ -90,6 +90,10 @@

 _OPSYS_SYSTEM_RPATH?=  /usr/lib

+.if !defined(CLTOOLS_VERSION)
+CLTOOLS_VERSION!=      pkgutil
--pkg-info=com.apple.pkg.CLTools_Executables | awk '$$1 == "version:" {
print $2 }'
+.endif
+
 .if !defined(OSX_VERSION)
 OSX_VERSION!=          sw_vers -productVersion
 .  if "${OSX_VERSION:R:R}" != "${OSX_VERSION:R}"

We can then use this in a variety of ways for conditional patching based
on the Xcode version.

Example output:

# pkgutil --pkg-info=com.apple.pkg.CLTools_Executables
package-id: com.apple.pkg.CLTools_Executables
version: 15.3.0.0.1.1708646388
volume: /
location: /
install-time: 1712319764

# pkgutil --pkg-info=com.apple.pkg.CLTools_Executables | awk '$1 ==
"version:" { print $2 }'
15.3.0.0.1.1708646388

Please let me know if you have any suggestions.
