GCC: libgcc/unwind-c.c:122:27: error: unused parameter ‘version’

[Blackhex]

Recent GCC commit Windows-on-ARM-Experiments/gcc-woarm64@71c7b44 added -Werror when building libgcc and it fails on this error:

Workaround

The current workaround is to add -Wno-error=unused-parameter to libgcc/config/aarch64/t-aarch64.
