Subject: [BUG?] macOS (Intel) build warnings: "ranlib: file … has no symbols" for aarch64 objects

Hi,
I'm building the master branch (commit 740a1494f4bf) on macOS (Intel Core i7) and encountered the following warnings during the make process:
/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/ranlib: file: libpgport.a(pg_popcount_aarch64.o) has no symbols
/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/ranlib: file: libpgport_shlib.a(pg_popcount_aarch64_shlib.o) has no symbols
/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/ranlib: file: libpgport_srv.a(pg_popcount_aarch64_srv.o) has no symbols
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.
