[PATCH v2 01/11] kbuild: rust_is_available: remove -v option

Miguel Ojeda
2023-06-16T00:17:03Z

From: Masahiro Yamada <masahiroy@kernel.org>

The -v option is passed when this script is invoked from Makefile,
but not when invoked from Kconfig.

As you can see in scripts/Kconfig.include, the 'success' macro suppresses
stdout and stderr anyway, so this script does not need to be quiet.
