Subject: [PATCH 1/3] riscv: vDSO: Remove --hash-style=both

When RISC-V borned, DT_GNU_HASH had already became the de-facto
standard so DT_HASH is just wasting storage space.  Remove the explicit
--hash-style=both setting and rely on the distro toolchain default,
which is most likely "gnu" (i.e. generating only DT_GNU_HASH, no
DT_HASH).

Following the logic of commit 48f6430505c0
("arm64/vdso: Remove --hash-style=sysv").
