Xcode 15 switched to a new implementation which has issues in some scenarios, for instance whenever asked to link against object files or dylibs created with GCC. A common reason for this is ports that need to use GCC to build fortran source code. OpenBLAS is a specific example that a number of ports use and thus are having issues linking against.

Yes, my careless mistake: it's the Xcode15 linker that's at issue here.
