glibc added support for .gnu.hash in 2006 and .hash has been obsoleted
for more than one decade in many Linux distributions.  Using
--hash-style=sysv might imply unaddressed issues and confuse readers.

Just drop the option and rely on the linker default, which is likely
"both", or "gnu" when the distribution really wants to eliminate sysv
hash overhead.

Similar to commit 6b7e2654 ("x86/vdso: Emit a GNU hash").
