Subject: [PATCH v2] sh: vsyscall: drop unnecessary cc-ldoption

Towards the goal of removing cc-ldoption, it seems that --hash-style=
was added to binutils 2.17.50.0.2 in 2006. The minimal required version
of binutils for the kernel according to
Documentation/process/changes.rst is 2.20.

Changes V1 -> V2:
* update commit subject and message as per Masahiro/Geert.

To Geert's question about minimum binutils versions; no change needed to
binutils.
