Subject: [PATCH] configure, meson: remove CONFIG_SOLARIS from config-host.mak
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

CONFIG_SOLARIS is only used to pick tap implementations.  But the
target OS is invariant and does not depend on the configuration, so move
away from config_host and just use unconditional rules in softmmu_ss.
