[v2] meson: Deprecate 32-bit host support

[PATCH v2 05/14] tcg: Link only when required in system mode

Posted by Richard Henderson 2 months ago

Rather than unconditional linkage via system_ss, conditinally
include the static library via specific_ss.  This will elide
the code when CONFIG_TCG is disabled for a specific target.
