It turns out that --hash-style=gnu is considered better than either of --hash-style=both or --hash-style=sysv, assuming your environment/platform supports it.
On amd64 with both Debian's and Alpine's linkers, --hash-style=gnu is the default.
This is especially relevant on MIPS (mips64le), where "ld: .gnu.hash is incompatible with the MIPS ABI" (so the linker sanely defaults to --hash-style=sysv there, as it should).
