This seems to be the relevant section of config.log:

Running both clang and GCC manually seem to also generate the following error, which seems to be the heart of the issue:
ld: warning: URGENT: building for OSX, but linking in object file (/var/folders/zh/_w3j4fws2mb80tmb617r_ycr0000gn/T//ccfp3Evo.o) built for iOS. Note: This will be an error in the future.
If this issue is with clang, is there a way to force building to use GCC? Alternatively, any sort of insight into why clang is behaving this way would be great. I've looked online for insight into the error message clang seems to be throwing, but I haven't yet found anything definitive. Thank you for your help.
