Log:
config-ix.cmake: Search for CMAKE_XCRUN before using it.

This was previously searched in CMakeLists.txt unconditionally but as of
r294371 it is only searched in some circumstances. Repeating the search
in config-ix.cmake to make this robust and hopefully fix the macOS
Asan+Ubsan jenkins build.
