Merge bitcoin/bitcoin#29072: build: use `-no_exported_symbols` on macOS
81d4dc8e8739df0e9a8e92f55071733f6500617b build: use -no_exported_symbols on macOS (fanquake)
Pull request description:
This reduces the size of the binary by ~1% when building with `--enable-reduce-exports`.
> -no_exported_symbols
> Useful for main executable that don't have plugins and thus need no symbol exports.
Can be tested with `dyld_info -exports src/bitcoind`. The only exported symbol should be `__mh_execute_header`.
