The build completes successfully and the compiled binaries appear to
function correctly.
These warnings appear to be related to the recent AArch64 (pg_popcount)
optimization commits (possibly 79e232ca013c and fbe327e5b465d). It seems
that on my Intel-based macOS system, the build process is generating
empty or placeholder object files for the AArch64-specific implementations.
While there is no functional impact in my environment, I'm reporting
this to ensure it's noted, as other macOS/Intel users might encounter
the same warnings during their build.
Probably not worth fixing, since this is an obsolescent platform.
The opposite situation also exists: On macOS ARM, an empty
pg_popcount_x86.c gets built, but apparently that linker doesn't warn
about that.
